Informal is intended as a combination of a Wiki notation filter and a free-form DB.
(After years on DokuWiki, I cannot live without Wiki notation and the existing filters do not satisfy me, sorry!)
Basics:
Wiki notation, being a hybrid between DokuWiki, MediaWiki and Redmine's Wiki
Wiki behaviour, i.e. define a link, click on it to create a new node (of the same node-type), being aware of permissions e.g.
Free-form database (FFDB): markup fields simply in the text, having these indexed and formatted
Define templates to be copied into the body field on a click or even on a function key (ajax?).
Definition of specific index tables for certain fields (later extension)
Not all is fully designed, yet.
For those not being aware of a free-form DB: just mark elements of the body as "fields" with fieldnames and the save will extract the fields. Apart from formatting them specifically, they will be stored in a search table.
There will surely be a filter definition to query the FFDB as well as a page to query it online. That simple search facility will translate the queries into SQL selects and show the results. Integration to views is to be checked!
