Alfresco tutorial: Custom content types including Share config and CMIS
It is hard to believe that the original version of my “Working With Custom Content Types” tutorial for Alfresco is almost five years old. That page has had over 37,000 unique visits since it was posted. It makes sense that it would be popular–creating a content model, exposing it to the user interface, and then performing CRUD functions against the repository through code are the first steps for most Alfresco development projects.
The fundamentals of content modeling haven’t changed since 2007, but since the original tutorial was posted the Alfresco Share web client has replaced Alfresco Explorer as the preferred user interface and the Content Management Interoperability Services (CMIS) API has become the first choice for writing remote code against the repository. That, combined with the influx of newcomers to the platform and a continued demand for how-to’s on the basics motivated me to revise the tutorial.
The second edition moves the Alfresco Explorer configuration to the Appendix and replaces it with steps for doing the same thing in Alfresco Share. I also moved the Java Web Services API to the Appendix and replaced that with Java examples that leverage the Apache Chemistry OpenCMIS API to create, update, query, and delete content in the repository. I’m executing the same queries as the first edition, just implemented using CMIS, so if you want to compare Lucene queries to CMIS Query Language, this is one place to do it.
I tested the document and the code against Alfresco 4.0.c Community. It may work on earlier versions, but no promises. It will probably work on Alfresco 4.0 Enterprise when it becomes available.
My goal is to revise the rest of the Alfresco Developer Series tutorials for Alfresco 4 over the next month or two so stay tuned.
