[redland-dev] CRUD with RDF triplestore and RDBMS

[Roman Bischoff]

Hi

Currently Im refactoring a (python based) web application with Resources
(REST style) in a relational DBMS (MySQL) and the respective metadata about
those resources in a redland RDF triplestore.

Now I wonder how other developers cope with CRUD requests that involve both,
the RDBMS and the redland RDF triplestore? 

Do you do create/update/delete as one request from the (web-) client, then
splitting it on the server side in two requests -- or would you rather have
two separate requests from the web client; one for the RDBMS and one for the
triplestore?
Was the answer different, if the web client is an "ajaxian" client?

Are you using transactions (unit of work) for creating, updating, deleting a
Resource in RDBMS and its metadata in Redland triplestore? 
How can you do such things as long as Redland doesn't support transactions?

If not, how do you prevent inconsistent data?


Thanks for some advice.

Regards,
Roman
