[rules-users] Metadata in Guvnor-created rules

[Michael Anstis]

Hell yeah - we always like receiving Community Contributions :)

I had a quick look at the code and it'll probably be more than a couple of
days (especially as you'd need to presumably get up to speed too?)

Depending on what meta-data you want there are different steps, but the
gist is to expose org.drools.guvnor.client.rpc.MetaData (constructed from
an AssetItem, retrieved from the Repository, and normally only sent to the
client-side) to the ContentHandlers' compile method. We could use the
AssetItem direct, but alot of the meta-data (especially Categories) is more
easily accessed if we populate MetaData. ContentHandlers build the various
DRL's - these would all need changing too to accept MetaData and (depending
on whether the auto-inclusion is enabled) add the Metadata.

Feel free to come along to #guvnor IRC channel for a chat.

You'd probably need to read
this<http://hudson.jboss.org/hudson/job/droolsjbpm-knowledge/lastSuccessfulBuild/artifact/droolsjbpm-introduction-docs/target/docbook/publish/en-US/html_single/index.html#gettingstarted>too.

With kind regards,

Mike
