[Steven Hawkins (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-2512?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12784464#comment-12784464 ] 

Steven Hawkins commented on TEIID-2512:
---------------------------------------

The simplest direction is to just deprecate the usage of the metadata text and instead prefer the usage of model properties.  At that point we still may want to expand upon the usage of the metadata element by allowing multiple and allowing for their own property sets.

> Currently when chaining the multiple Metadata Repositories in VDB.xml they are defined using a comma separated list on <metadata> element. Any "context" specific value is submitted via "TEXT" element under <metadata>.
> However with above only one TEXT value can be defined, and if multiple repositories need to use the TEXT value there is no way to distinguish who is the owner of the data.
> A Enhancement is required to be able to define multiple <metadata> elements in the vdb.xml to chain the repositories instead using the comma separated list.
