We have a CakePHP 2.5 app for which we'll very soon be building a learning centre/knowledge base. Craft is one of the tools we're considering for that due to its apparent suitability for content editors to create longform, mixed content consisting of text, images and videos without ending up with junk HTML.
For a couple of reasons, it might be preferable for us to have the learning centre content served as part of the app rather than via Craft at a subdomain, so we'd like to know how we would pull in just the generated HTML Content for the actual article content from Craft for embedding within the app's layout.
The learning centre will have four categories, each with an unknown number of articles.
We'd need to be able to reference each article, and maybe each category, from within the app as users can be set parts of the learning centre as tasks.
