             Summary: Map the ODF XML RelaxNG schema into a GraphDB for Analysis
                 Key: ODFTOOLKIT-458
                 URL: https://issues.apache.org/jira/browse/ODFTOOLKIT-458
             Project: ODF Toolkit
          Issue Type: Wish
            Reporter: Svante Schubert
            Assignee: Svante Schubert


*PROBLEM*
The ODF XML (RelaxNG) schema is too big to easily read or be analysed by humans.
In version ODF 1.2 it has 598 elements and 1300 attributes.


*SOLUTION*
Therefore I would love to load the ODF XML RelaxNG schema into a GraphDB (for instance Neo4J) and do some basic analysis (sanity checks) on it.
For instance, I am curious on query questions as:
a) is a certain ODF element able to become nested (e.g. <text:p>)
b) is every ODF element with an ID allowed to exist more than once  (this issue occurred)
c) what is the minimum mandatory ODF XML document 
etc.

These queries could help a lot to understand and test the XML schema.

Certainly, I would love to have afterwards more tooling.
For instance, to be able to add metadata to the nodes to categorise nodes (which are meant for metadata, styles, text container, which are just plain boilerplate (e.g. office:body)

The idea is to improve the generation of ODFDOM source code to allow easier maintainability.


*DESIGN IDEA*
Instead of reading plain RelaxNG, I thought it might be a better idea to read already a 'normalised' document the dumped internal model from MSV. You may find the dump for each ODF version as test references from 
<ODFTOOLKIT_ROOT>/generator/schema2template/src/test/resources/examples/odf
e.g. http://svn.apache.org/viewvc/incubator/odf/trunk/generator/schema2template/src/test/resources/examples/odf/odf12-msvtree.ref?revision=1167972&view=co 

NOTE: 
You may find more about the information on the dump and the MSV model in:
<ODFTOOLKIT_ROOT>/generator/schema2template/src/main/java/schema2template/example/odf/OdfHelper.java
and
<ODFTOOLKIT_ROOT>/generator/schema2template/target/apidocs/index.html
https://incubator.apache.org/odftoolkit/0.6.2-incubating/schema2template/

I would love to have a discussion on further thoughts of yours on the list.
