I need a good book for Drools, JBPM and Guvnor to get a good understanding of workflow and
rule-engine. I need to create a workflow based application and the book will be helpful to
me in my development and understanding.

Subject: Re: [rules-users] Guvnor REST APIs - what rule features are supported?
As mentioned, I'm trying to build a custom rule editor.Â
I'm looking at the following approaches:
* Guvnor REST - seems very limited - but could be used for simply CRUD of DRL.
* Re-using Guvnor code, such as webapp-core - apparently hasÂ undocumentedÂ dependencies.
Also, its a large code base - would take time to get familiar.Â
* A DSL to DRL converter - for complex rules, which we have, this will also be complex
* using RuleML
I would be very interested to hear how others have tacked this challenge, or any
recommendations from drools users/developers.

You can however, and as some do, download the source for a rule, deserialise this into
Guvnor's *internal* model (depending on the type of rule), modify this
programmatically, serialise back to source and use REST to write it back to Guvnor.
"Source" as used above could be XML although some assets are stored as DRL.
Also all models should be considered as *internal* (I.e. not public) as we don't
undertake that they are compatible between releases (although in reality they have changed
very little, other than guided decision tables).

I saw a thread a few days ago asking about how to enable/disable rules using
the guvnor REST Api - only to find that that functionality does not exist.
What other functionalities are not covered by the REST apis?
For example, can we add calendars using the REST api?
What about salience, no-loop, activation group, agenda group, duration?
We are looking to build a custom UI for editing rules, using the Guvnor REST
apis, and but if there is limited coverage, then we will need to find an
