Alfresco open source content management

Highlights from the Alfresco Meetup in Chicago

Other than the drenching I received between the blue line and the hotel (both coming and going) I thoroughly enjoyed my time in Chicago with the Alfresco crew last week. I ran into some Optaros customers, past colleagues, blog and book readers, and even some consultants from another firm who told me they came across some code I wrote for a client many years ago that they now support. (It was a custom Documentum WDK app for a certain carbonated beverage company that was actually pretty cool at the time, but I’d love to re-do it on an open stack).

The day was well-spent with Matt Asay kicking off with a state of the union, of sorts, followed by a couple of sessions from Michael Uzquiano, Alfresco product manager. I thought Uzi’s discourse on the macro- and micro-economic climate was interesting, but a bit arduous. Yes, we’re in some tough times and that’s good for open source. Check. Next slide. My favorite part of his talks were on the Alfresco roadmap (see Highlights, below).

Ed Wentworth, from Orbitz, gave a cool talk on how they’re using Alfresco. Ed’s team is implementing what I think is a best practice pattern: Services-Oriented Content Management. Orbitz has a lot of dynamic sites built on content chunks, not complete, fully-baked pages. So they leverage Alfresco’s strengths as a core repository, and then expose the repository as a service to the front-end (and to other services). They use the web client only for atypical or administrative interactions, and custom Share components and Surf apps for content authoring.

Orbitz also leverages an “Enterprise Content Bus” comprised of a ServiceMix ESB, BPM, and a rules engine (more info on ECB here and here). The ECB is primarily focused on orchestrating content-centric processes like content routing and delivery. Not everyone is going to need an ECB but if you’ve got anything that resembles a content production pipeline, it can really make your processes much more flexible with less code.

TSG did a cool demo on an open source solution for annotating attachments (screencast). It looks like it is still in dev mode but it’s got a great start and hopefully they’ll continue to enhance this and make it available to the community.

I did the Alfresco-Drupal CMIS integration demo (screencast) which seemed to go over well. Most people in the room acknowledged that they have more than one CMS, so there was interest something that could enable multiple web sites talking to one or more back-end CMS repositories using a standard API (CMIS).

At the end of the day a sort of “Everything you wanted to know about Alfresco but were afraid to ask” roundtable formed which was cool. I tried to demo the Alfresco-Django integration we’ve been working on. It worked on the plane and works now, but the demo gods chose that very day to expire my Alfresco license, and although hard to miss, I didn’t notice that as the root of my problem until after the meeting. It’s all good now so if you’ll be at the San Francisco event next week and want to see Django and Alfresco working together, let me know.

Highlights of the Alfresco Talks

  • Alfresco now has 1000 paying customers. Matt says it took Documentum many years to get to that point. With the price disparity, obviously, Alfresco needs many more customers than Documentum to thrive, but still, that’s quite an achievement.
  • There’s a Groovy renderer coming to Surf after 3.2.
  • Speaking of Surf, I’m not sure when it is coming, but Spring WebFlow is now being integrated into Surf which is much-needed.
  • If you’re looking for CMIS resources, CMISDev.org is a new site aimed at pulling a lot of that stuff together.
  • 3.2 Labs targeted for June
  • 3.2 Enterprise targeted for September 2009
  • 3.3 Labs/Enterprise targeted for 1Q 2010
  • 4.0 Labs/Enterprise targeted for 2nd half of 2010

The 3.2 release is shaping up to be pretty major. Here are some of the things planned for 3.2 that caught my ear:

Surf Mobile. This is an addition to the Surf framework that makes it easier to develop Surf apps that work well on the iPhone, although audience members said the demo site was also usable on their Blackberries.

New Form Service. Today you’ve got “property sheets” in the Explorer client which are driven by the content model and the web-client configuration XML, web forms in WCM which are defined using XSD, and custom forms in Surf which aren’t defined using any kind of framework at all. The new form service will provide a single form definition/presentation framework across the entire Alfresco platform. It’s a Good Thing.

IMAP integration. This allows you to use your Outlook client (and Thunderbird and whatever else you use that knows IMAP) to get things into and out of the repository. One use for this is to archive email by dragging-and-dropping mail into mail folders which are backed by Alfresco. Another is to easily snag content from the repo without leaving the mail client. I don’t know if it will be in there, but a great feature would be to allow me to drag-and-drop a piece of Alfresco content onto my message which would then get translated into the download URL rather than a file attachment.

Clustering. Several attendees fell to the ground and wept, overcome with emotion, when Uzi said 3.2 would support real clustering of both the DM and WCM repositories. Clustering is something that has bedeviled complex Alfresco implementations. I’ll maintain my composure until I see this actually working.

Index refactoring. Ever do a search that fails to return a piece of content you know is in the repo? Or, the other way, when you see something that you know was deleted? Do you mark the time it takes to reindex your repository (to fix index inconsistencies) by how many times the moon rises and sets? I have no idea whether any of these issues will get better in 3.2 but hearing “index” and “refactor” in the same sentence makes me hopeful.

All-in-all I’d say it was one of the better Alfresco-led meetups. I’m looking forward to reconnecting with many of you next week in San Francisco. I’ll see you there.

Drupal, Django, and Alfresco in Chicago

I’ll be in Chicago tomorrow for the Alfresco Meetup. I’ll be speaking during the Barcamp on Alfresco and Drupal integration with CMIS (module, screencast). I’ll also have the Alfresco-Django integration running on my laptop. I may not have time to show Alfresco-Django during my slot, but I’ll be happy to stick around and do informal demos and talk about either integration if you’re interested because I’d like your feedback on it.

Apache Chemistry: A Proposed Reference CMIS Implementation

Kas Thomas, over at CMSWatch, says a new Apache project is in the works. Chemistry is a reference CMIS implementation that has committers from Day, Alfresco, and Nuxeo. The goal is to provide a vendor-neutral reference implementation and compatibility tests around the proposed CMIS specification.

It looks like this will be a standard set of REST APIs and SOAP services that implement the CMIS spec and hook into a back-end repository. Not surprisingly, the first back-end the Chemistry team plans to support is Apache Jackrabbit, Apache’s reference implementation of the JCR API.

Customizing Alfresco Share: Five things to watch out for

Alfresco Share is a team-centric collaboration tool. It’s really cool and our clients have been reacting very positively to it. When customers see the AJAXalicious UI, a common reaction is to want to take the next 5 projects on their list and “do them on Share”.

In cases where the functional requirements closely resemble team collaboration, that can be a great choice. In others, it’s an abuse of the tool. Just like a lot of things in software and life, just because you can doesn’t mean you should. (Remind me to tell you the story about building a tennis court reservation system in Lotus Notes some time).

Anyway, let’s assume you’ve got a set of requirements that reasonably resembles team-based collaboration, but some of Share’s tools (wiki, blog, document library, calendar, and recently, bookmarks) don’t work exactly the way you need them to. I’m not talking about adding new, self-contained custom components. This is specifically about customizing the out-of-the-box Share components. With that in mind, here are five areas where even simple Share customization efforts could take longer than you might think.

Custom Metadata

In its current incarnation, if you have custom metadata you want to display when looking at document detail, that’s code you have to write. Alfresco’s Mike Hatfield said, via Twitter, that the 3.2 Forms Service will make this better, so that’s good. If your Share sites contain simple documents that use only out-of-the-box metadata, this won’t be an issue for you.

Custom Workflows

Currently, in Share, there are a couple of places where the jBPM workflow engine is used. First, when you invite someone to a site, that kicks off a workflow. Second, you can “assign” an advanced workflow to a document in the document library.

The first issue is that the workflow submission dialog includes only the two out-of-the-box, document-centric workflows, “Ad hoc” and “Review and Approve”. It won’t show any custom workflows you’ve deployed. The workflow modal is not inspecting the workflow UI configuration like the web client does, so even if you got your workflows to show up in that list, the form wouldn’t have the custom workflow metadata you need to launch your custom workflow properly.

When you log in to Share, you’ll see a “My Tasks” dashlet. This gives you hope that maybe that dashlet could manage tasks for any workflow. Unfortunately, it only works with the “invite user” workflow and the two document-centric, OOTB workflows.

Long story short, Share isn’t set up to work with custom workflows out-of-the-box. If you’ve got custom workflows that need to work in the Share context, you’ll need to write your own dialogs for launching the workflow and your own component for managing workflow tasks.

YUI Bubbling Events

Share makes heavy use of YUI Bubbling Events. This results in a great end-user experience–the Share components communicate with each other and refresh themselves via AJAX without page refreshes. But it does mean there’s a bit of a learning curve when following the same pattern to implement your customizations if your team has never worked with the bubbling library before. It can get kind of thick in places.

Incidentally, all of the YUI stuff is part of Share, not Surf, which is the framework used to build Share. If you’re building your own Surf app you’ll need to grab the YUI libraries (or any other libraries you want to use) yourself. It’s the same for the Flash pieces (multi-document upload, document preview). It keeps Surf light, but if you want to incorporate that kind of functionality into your Surf app, some assembly will be required.

Code Sprawl

In Share, every module has as least one JavaScript file. For example, the Document Library has six different JavaScript files weighing in at about 136KB. Sometimes what should be a simple change (adding a button, creating a new modal) requires changes to every one of those files. This combined with grokking the bubbling events translates into potentially lengthy development cycles for stuff that you wish would be quick.

Theming

The main CSS file for Share is in the themes directory. But changing that will only affect the global dashboard header and the site dashboard header. If you want to change the theme for everything in Share, including individual tools, you have to change each tool’s CSS file. Those CSS files live in the “modules” directory. It would be nice if it were easier to implement site-wide or global themes.

Adding your own Components/Tools

The impact of these issues are lessened somewhat if you are adding your own components or tools instead of customizing what’s already there. It’s easy to write your own dashlets that show up on the global dashboard or the site dashboard. And with a little work, you can write dashlets that talk to each other using YUI Bubbling Events, just like the OOTB dashlets. The area for improvement is in skinning, configuring, and extending the out-of-the-box tools.

Share Your Thoughts on Share

There’s no doubt that Share is a cool application for team-based collaboration. I didn’t expect it to be configurable to the Nth degree right away, and we may be pushing the limits of its intended use. I’m curious to hear from others who have been tweaking the app: Have you worked through these issues? Are there other examples of specific extension points Alfresco could address to make your lives easier?

Alfresco User Interface: What are my options?

People often need to build a custom user interface on top of the Alfresco repository and I see a lot of people asking general questions about how to do it. There are lots of options to consider. Here are four options for creating a user interface on top of Alfresco, at a high level:

Option 1: Use your favorite programming language and/or framework to talk to Alfresco via REST or Web Services. PHP? Python? Java? Flex? Whatever, it’s up to you. The REST API is nice because if you can’t find a URL that does what you need it to out-of-the-box, you can always roll-your-own with the web script framework. This option offers the most flexibility and creative freedom, but of course you might end up building constructs or components that you may have gotten “for free” from a higher-level framework. Optaros‘ streamlined web client, DoCASU, built on Ext-JS, is one freely-available example of a custom UI on top of Alfresco but there are others.

Option 2: Use Alfresco’s Surf framework. Alfresco’s Surf framework is just that–it’s a framework. Don’t confuse it with Alfresco Share which is a team-centric collaboration client built on top of Surf. And, don’t assume that just because a piece of functionality is in Share it is available to you in the lower-level Surf framework. You may have to do some extra work to get some of the cool stuff in Share to work in your pure Surf app. Also realize that Surf is brand new and still maturing. You’ll be quickly disappointed if you hold it to the same standard as a more widely-used, well-established framework like Seam or Django. Surf is a good option for quick, Alfresco-centric solutions, especially if you think you might want to leverage Alfresco’s browser-based site assembly tool, Web Studio, at some point in the future. (See Do-it-yourself Alfresco Surf Code Camp).

Option 3: Customize the Alfresco “Explorer” web client. There are varying degrees to which you can customize the web client. On one end of the spectrum you’ve got Freemarker “presentation templates” followed closely by XML configuration. On the other end of the spectrum you’ve got more elaborate enhancements you can make using JavaServer Faces (JSF). Customizing the Alfresco Explorer web client should only be considered if you can keep your enhancements to an absolute minimum because:

  1. Alfresco is moving away from JSF in favor of Surf-based clients. The Explorer client will continue to be around, but I wouldn’t expect major efforts to be focused on that client going forward.
  2. JSF-based customizations of the web client can be time-consuming and potentially complex, particularly if you are new to JSF.
  3. For most solutions, you’ll get more customer satisfaction bang out of your coding buck by building a purpose-built, eye-catching, UI designed with your specific use cases in mind than you will by starting with the general-purpose web client and extending from there.

Option 4: Use a portal, community, or WCM platform. This includes PHP-based projects like Drupal (Drupal CMIS Screencast) or Joomla as well as Java-based projects like Liferay and JBoss Portal. This is a good option if you have requirements that match up well with the built-in (or easily added-on) capabilities of those platforms.

It’s worth talking about Java portal servers specifically. I think people are struggling a bit to find The Best Way to integrate Alfresco with a portal. Of course there probably is no single approach that will fit every situation but I think Alfresco (with help from the community) could do more to provide best practices.

Here are the options you have when integrating with a portal:

Portal Option 1: Configure Alfresco to be the replacement JSR-170 repository for the portal. This option seems like more trouble than it is worth. If all you need is what you can get out of JSR-170, you might as well use the already-integrated Jackrabbit repository that most open source portals ship with these days unless you have good reasons not to. I’m open to having my mind changed on this one, but it seems like if you want to use Alfresco and a portal, you’ve got bigger plans that are probably going to require custom portlets anyway.

Portal Option 2: Run Alfresco and the portal in the same JVM (post). This is NOT recommended if you need to scale beyond a small departmental solution and, really, I think with the de-coupling of the web script engine we should consider this one deprecated at this point.

Portal Option 3: Run the Alfresco web script engine and the portal in the same JVM. Like the previous option, this gives you the ability to write web scripts that are wrapped in a portlet but it cuts down on the size of the web app significantly and it frees up your portal to scale independently of the Alfresco repository tier. It’s a fast development cycle once you get it set up. But I haven’t seen great instructions for setting it up yet. Alfresco should document this on their wiki if they are going to support this pattern.

Portal Option 4: Write your own portlets that make services calls. This is the “cleanest” approach because it treats Alfresco like any other back-end you might want to integrate with from the portal. You write custom portlets and have them talk to Alfresco via REST or SOAP. You’ll have to decide how you want to handle authentication with Alfresco.

What about CMIS?

CMIS fits under the “Option 1: Use your favorite programming language” and “Portal Option 4: Write your own portlets” categories. You can make CMIS calls to Alfresco using both REST and SOAP from your own custom code, portlet or otherwise. The nice thing about CMIS is that you can use it to abstract the underlying repository so that (in theory) your front-end code will work with different CMIS-compliant back-ends. Just realize that CMIS isn’t a fully-ratified standard yet and although a CMIS implementation is in the Enterprise version of Alfresco, it isn’t clear to me whether or not you’d be supported if you had a problem. (The last response I saw on this specific question was a Peter Monks tweet saying, “I don’t think so”).

The CMIS standard should be approved by the end-of-the-year and if Alfresco’s past performance is an indicator of the future, they’ll be the first to market with a production-ready, fully-supported CMIS implementation based on the final spec.

Pick your poison

Those are the options as I see them. Each one has trade-offs. Some may become more or less attractive over time as languages, frameworks, and the state of the art evolve. Ultimately, you’re going to have to evaluate which one fits your situation the best. You may have a hard time making a decision, but you have to admit that having to choose from several options is a nice problem to have.

Curl up with a good web script

Curl is a useful tool for all sorts of things. One specific example of when it comes in handy is when you are developing Alfresco web scripts. On a Surf project, for example, you might divide into a “Surf tier” team and a “Repository tier” team. Once you’ve agreed on the interface, including both the URLs and the format of the data that goes back-and-forth between the tiers, the two teams can start cranking out code in parallel.

If you’re on the repo team, you need a way to test your API, and you probably don’t have a UI to test it with (that’s what the other team’s working on). There are lots of solutions to this but curl is really handy and it runs everywhere (on Windows, use Cygwin).

This post isn’t intended to be a full reference or how-to for curl, and obviously, you can use curl for a lot of tasks that involve HTTP, not just Alfresco web scripts. Here are some quick examples of using curl with Alfresco web scripts to get you going.

Get a ticket

It’s highly likely that your web script will require authentication. So the first thing you do is call the login web script to get a ticket.

curl -v "http://localhost:8080/alfresco/service/api/login?u=admin&pw=somepassword"

Alfresco will respond with something like:

<?xml version="1.0" encoding="UTF-8"?>
<ticket>TICKET_e46107058fdd2760441b44481a22e7498e7dbf66</ticket>

Now you can take that ticket and append it to your subsequent web script calls.

Any web script you’ve got that accepts GET can be tested using the same simple syntax.

Post JSON to your custom web script

If all you had were GETs you’d probably just test them in your browser. POSTs, PUTs and DELETEs require a little more doing to test. You’re going to want to test those web scripts so that when the front-end team has their stuff ready, it all comes together without a lot of fuss.

So let’s say you’ve got a web script that the front-end will be POSTing JSON to. To test it out, create a file with some test JSON, then post it to the web script using curl, like this:

curl -v -X POST "http://localhost:8080/alfresco/service/someco/someScript?alf_ticket=TICKET_e46107058fdd2760441b44481a22e7498e7dbf66" -H "Content-Type: application/json" -d @/Users/jpotts/test.json

By the way, did you know that starting with 3.0, if you name your controller with “.json” before the “.js” the JSON will be sitting in a root variable called “json”?  So in this case instead of naming my controller “someScript.post.js” I’d name it “someScript.post.json.js” and then in my JavaScript, I can just eval the “json” variable that got created for me automatically and start working with the object,  like this:

var postedObject = eval('(' + json + ')');
logger.log("Customer name:" + postedObject.customerName);

Run a CMIS query

With 3.0 Alfresco added an implementation of the proposed CMIS spec to the product. CMIS gives you a Web Services API, a RESTful API, and a SQL-like query language. Once you figure out the syntax, it’s easy to post CMIS queries to the repository. You can wrap the CMIS query in XML:

<cmis:query xmlns:cmis="http://www.cmis.org/2008/05" >
<cmis:statement><![CDATA[select * from cm_content where cm_name like '%Foo%']]></cmis:statement>
</cmis:query>

Then post it using the same syntax as you saw previously, but with a different Content-Type in the header, like this:

curl -v -X POST "http://localhost:8080/alfresco/service/api/query?alf_ticket=TICKET_e46107058fdd2760441b44481a22e7498e7dbf66" -H "Content-Type: application/cmisquery+xml" -d @/Users/jpotts/cmis-query.xml

Alfresco will respond with ATOM, but it’s a little verbose so I won’t take up space here to show you the result. Also, I noticed this bombed when I ran it against 3.1 Enterprise but I haven’t drilled down on why yet.

Create a new object using CMIS ATOM

Issuing a GET against a CMIS URL returns ATOM. But CMIS URLs can also accept POSTed ATOM to do things like create new objects. For example, to create a new content object you would first create the ATOM XML:

<?xml version="1.0" encoding="utf-8"?>
<entry xmlns="http://www.w3.org/2005/Atom" xmlns:cmis="http://www.cmis.org/2008/05">
<title>Test Plain Text Content</title>
<summary>Plain text content created via CMIS POST</summary>
<content type="text/plain">SGVyZSBpcyBzb21lIHBsYWluIHRleHQgY29udGVudC4K</content>
<cmis:object>
<cmis:properties>
<cmis:propertyString cmis:name="ObjectTypeId"><cmis:value>document</cmis:value></cmis:propertyString>
</cmis:properties>
</cmis:object>
</entry>

Note that the content has to be Base64 encoded. In this case, the content is plain text that reads, “Here is some plain text content.” One way to encode it is to use OpenSSL like “openssl base64 -in <infile> -out <outfile>”. The exact syntax of ATOM XML with CMIS is the subject for another post.

Once you’ve got the XML ready to go, post it using the same syntax shown previously, with a different Content-Type in the header:

curl -v -X POST "http://localhost:8080/alfresco/service/api/node/workspace/SpacesStore/18fd9821-42a5-4c6a-86d3-3f252679cf7d/children?alf_ticket=TICKET_e46107058fdd2760441b44481a22e7498e7dbf66" -H "Content-Type: application/atom+xml" -d @/Users/jpotts/testCreate.atom.xml

The node reference in the URL above is a reference to the folder in which this new child will be created. There’s also a similar URL that uses the path instead of a node ref if that’s more your thing.

Refreshing Web Scripts from Ant

One of the things you do quite frequently when you develop web scripts is tell Alfresco to refresh its list of web scripts. There are lots of ways to automate this, but one is to create an Ant task that uses curl to invoke the web script refresh URL. This lets you deploy your changes and tell Alfresco to refresh the list in one step (and makes sure you and your teammates never forget to do the refresh).

<target name="deploy-webscripts" depends="deploy" description="Refreshes the list of webscripts">
<exec executable="curl">
<arg value="-d"/>
<arg value="reset=on"/>
<arg value="http://${alfresco.web.url}/service/index"/>
</exec>
</target>

In this example, the “deploy” ant task this task depends on is responsible for copying the web scripts to the appropriate place in the exploded Alfresco WAR. (Thanks to my colleague Eric Shea (http://www.eshea.net/2009/01/30/alfresco-dev-survivors-kit-part-1/) for this tip).

So there you go. It’s not Earth-shattering but it might give you a productivity boost if you don’t already have curl or an alternative already in your bag of tricks.

Screencast: Alfresco-Drupal CMIS Integration Demo

UPDATE: Screencast now lives here:

I’ve created a new screencast that shows the Alfresco-Drupal CMIS integration in action over at Optaros Labs. The screencast shows content moving back-and-forth between Alfresco and Drupal, content being displayed in a Drupal site that lives in Alfresco, and a CMIS CQL query being executed against the Alfresco repository from Drupal.

The Drupal CMIS module and the CMIS Alfresco module are available at Drupal.org.

Alfresco 3.1 Enterprise is a significant release for WCM users

I don’t typically write a post every time a vendor releases a new version of software but Alfresco 3.1 Enterprise, which became available for download on Tuesday, is a significant release. Users of 2.2, who had previously been asked not to upgrade to 3.0, should now upgrade to either 2.2 SP3 or 3.1. All of the fixes in 2.2 SP3 are included in the 3.1 release. If you are currently on 2.2 SP3, the biggest reason to move to 3.1 would be to take advantage of Alfresco Share. Conservative users may decide to wait until 3.1.1.

One big change with 3.1 is that modified items are now merged with the Staging sandbox asynchronously. That means when submitting modified items, users are immediately returned to the sandbox list and will still see the modified items until they are committed. In a cursory test of this, I was surprised at how long it took for those changes to leave my Modified Items list. Maybe the polling interval is configurable.

This change affects the out-of-the-box WCM submission workflow. So if you created your own custom WCM submission workflow, you’re going to need to make some changes. The required changes are documented in the release notes, or you can take a look at the new submission workflow to get the gist.

Another new feature of Alfresco 3.1 is the REST API for WCM. A lot of URLs you probably already created on your own are included. The new API includes things like adding users to web projects, creating user sandboxes, creating, updating, and deleting assets, submitting assets, and more. Even if you already built these yourself, you should take a look to see if these meet your needs. Why continue to maintain your own custom code?

The 3.1 release also marks a shift in Alfresco’s “two flavors” approach. According to John Newton (post), Alfresco is looking for ways to entice large Enterprise users to migrate from Labs to Enterprise. So they’ve created functionality that they feel only appeals to large Enterprises and are making it available only to people paying for subscriptions. This includes things like monitoring (JMX, Hyperic plug-in), proprietary database extensions, and clustering.

Newton says 100% of the source code will still be available for both releases and that fixes made in Enterprise will be made available in the next Labs release (although he didn’t say how long Labs releases will lag behind Enterprise).

Other noteworthy 3.1 fixes or enhancements include:

  • No one (not even admin) can write to a Staging sandbox in WCM.
  • Share now includes a “Links” component (which means I don’t have to finish coding the “Bookmarks” component we started but never finished). There are numerous other Share enhancements around Calendar, rich text editing, and previewing.
  • Actions can now have AND/OR conditions and can trigger on property values.
  • A new group called ALFRESCO_ADMINISTRATORS has been created that makes it much easier to designate administrator users other than admin.

See the release notes for a full list of Jira tickets addressed by the release.

Webinar: Developer’s Intro to Alfresco Part 3: Web Scripts & Surf

Part 3 of the “Developer’s Introduction to Alfresco” webinars is today at 12 Eastern (GMT – 5). I’ll be talking about web scripts, Surf, and CMIS. The format will be the same as the first two parts: you’ll watch a pre-recorded presentation for about 30 minutes, then I’ll do at least a 30 minute live Q&A session.

Also, I know I’ve been slow in getting this posted, but the Part Two presentation and Q&A recordings are available at Alfresco’s on-demand events page.
