Semantic MediaWiki
For certain types of resources, you might want to consider using Semantic MediaWiki and the Semantic Forms extension. You might want to check out http://textbookrevolution.org and http://wiki.creativecommons.org/Case_Studies as a couple ways it can be used. It makes it easy to enter (form-based) structured data and easy to query the data and display it in various ways. You can also export data (JSON, CSV, RDF, etc).
