You're the first one I see to have this need so I'm curious to
understand what's your use case first. My belief is that you're not
using XWiki properly.
Me again jumping in others' threads! :-(
Before XWiki arrives to our lives, their are much easier now, we use
Oracle and MySQL RDBMS to store experimental data. Personal data are
stored in a LDAP enabled directory service.
To be able to read/write to/from these repositories from XWiki has been
always an objective, but always delayed as we need have more urgent
issues to solve!
Harikrishnan's entry put the issue top in our to-do list!
Let's see if this make sense for you:
We use XWiki to create a collaboration environment: the whole
team can contribute to a new document. XWiki user's database is
synchronized with our eDirectory directory service by using LDAP.
New documents include "structured" text (heading1, heading2,
body, list,...), pictures and code.
Among "code" we include small "programs" generating graphs and
tables from the relational data sharing MySQL with XWiki as RDBMS. We
use R to generate graphs and tables: to be able to call R directly from
XWiki will be a great plus, but it is not strictly required at the
current stage of development.
Documents will be eventually included as "code" as far as we
would like to use LaTeX as typesetting tool.
With this work flow (I think it is a "correct" use for XWiki), the
first thing to solve is what Harikrishnan is asking for... and ready to
contribute with!!!
So, these are only my two cents. I do hope it makes sense and helps to
clarify the problem, doesn't it?
