Subject [jira] Commented: (JCR-877) Add more flexibility in the mapping
Date Thu, 29 May 2008 16:33:45 GMT

--------------------------------------

Hi  Christophe,
you propose to generate CND from java-class definition. It sound very similar with Webservice-related
approaches with "WSDL-first" vs. "implementation first "...
..at the moment we decided to use the CND-first approach. This way produce java-source in
next steps :
1. CND design
2. CND -> XML (NodeTypeReader+NodeTypeWriter)
3. XML--XSLT-->OCM Java annotatated code.
4. Javac-validation + JavaDoc.
Do u see some disadvantages in such way? 

As for me OCM-mapping file has identicalinformation as JCR-nodedefinition xml (for ex $JR_HOME/repository/nodetypes/custom_nodetypes.xml
  )  Am i right?

> Sometime, it should be interesting to map to a different jcr node structure. 
> Here is an example, for a class "File", we can have : 
> public class File
> {
>     private String mimeType;
>     private String encoding;
>     private InputStream data;
>     private Calendar lastModified;
>     // Add getters/setters
> }
> and in terms of JCR structure, we can have : 
> nt:file
>     jcr:content
>         jcr:mimeType
>         jcr:encoding
>         jcr:data
>         jcr:lastModified
> So, the jcr:content node is an extra node to specify in the mapping file.
