Hi devs, Right now we bundle 3 HBM files for DBs we don’t support: derby, mssql and db2. So we can’t guarantee that they work and it’s possible they don’t anymore after the Hibernate upgrade. I propose to do the following: * Create a single repo in contrib to host them. hibernate-mappings-extra or something like that * Document how to install these mappings in the page for each of these DBs. For ex for DB2 it would be documented on https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Installation/…, etc. The only downside is that when we make chages to the HBM files we support we won’t make the same adjustements for these non supported DBs… OTOH we don’t support them... WDYT? Thanks -Vincent
