Hey,

In-line editing gets rather tricky when parser functions are involved.
Since most SMW data ends up being passed via templates, having an inline
editor for templates would go a long way, but I think this already exists
to some extend. Editing arbitrary properties is a lot harder, since they
might be set using the extended link syntax or #set, both of which can take
things such as template parameters and the results of other functions. And
they might even just be computed by SMW (ie Modification date).

So I'd be very careful to not reinvent the wheel, since effort in this
direction has already been done, and also not underestimate the difficulty
to get this to work nicely.

>  Do I have to make changes on the server side to the SMW-Tables or will
this automatically happen after a page refresh with the new page content?

The data held in the SMW tables is "secondary data" in the sense that it is
computed by parsing the actual page content. It should always be possible
to get rid of the data in the tables and regenerate it from the actual page
content. So if you go write directly to the tables and not have it changed
in the actual page, you'll run into problems. So a working (although maybe
not very efficient) approach would be modifying the page content and just
saving it, without caring at all how SMW deals with the data. In this case
your integration with SMW would mainly consist of understanding the
extended link syntax and #set.

Good luck with your project :)

Cheers

Hello Jeroen,

thank you for answering. Now I see the problems too and will reduce the
project accordingly to provide only managing of well declared text parts in
the front end while announcing the exceptions of functionality. By the way
just for interest, could you answer the following questions too?

- Is there a db-scheme available for SMW? 

- Do you know a parser-funktion of object parser or another object which
will turn wiki-text into HTML-markup?

thank you, stevie

Hey,

We do not currently have any documentation on the database schema used by
SMW. You should probably not have to know about it though, and use SMWs
store abstraction layer to access the database. Nischay is currently
modifying the MySQL schema for performance reasons, so it'll look different
in the near future.

You're better of asking this on the wikitech mailing list :)

Cheers
