[fulcrum] RFC for contributing two services ....

[Siegfried Goeschl <si...@it20one.at>]

Hi folks,

I want to contribute two services for now which can be found at 
http://84.113.204.124/download/

+) fulcrum-resourcemanager 
(http://84.113.204.124/download/fulcrum/resourcemanager/target/docs/)
+) fulcrum-groovy 
(http://84.113.204.124/download/fulcrum/groovy/target/docs/)

1) Ad Fulcrum ResourceManager Service
==================================
I need a way to decouple the Groovy service from the persistence 
mechanism. This should provide two basic features

1.1) location transparency since the scripts could be stored in a DB as 
well. Therefore the service
exposes CRUD functionality

1.2) the locator allows to search for a named resource up the directory 
tree. I use this pattern heavily for my work to add
customization based on a context to look up a resource.

I also have a fulcrum-dom4jxslt-service to be contributed which depends 
on the ResourceManager as well.

As Eric Pugh pointed out there is an overlap with Turbine and 
commons-configuration ... any opinions out there?!

2) Ad Fulcrum Groovy Service
==================================

Allows invoking Groovy scripts and provides access to the Avalon 
infrastructure.

3) Ad "urn:avalon.temp"
==================================

Yes - it is a standard Avalon value. Ceck out 
http://wiki.apache.org/avalon/AvalonContextSurvey and 
http://wiki.apache.org/avalon/AvalonStandards - I'm definitely adding 
urn:avalon:name.

I use "urn:avalon:temp" to dump the stuff which blows up my logfile such 
as the result of a XSL transformation. As a filename I user 
<servicename>_state.extension, e.g
DOM4JXSLTService_input.xsl and DOM4JXSLTService_result.xml. In my 
opinion a single temp directory for all apps is fine since I use the 
temp directory of Java as default.

Thanks in advance

Siegfried Goeschl

PS: Eric - you could still look if the things integrate nicely with 
Fulcrum  ... :-)

Sigi,

Can you forward this to the Turbine list?  We need to make sure that folks
on turbine-dev see all Fulcrum related posts as that IS the mailing list for
now.  If we feel that the traffic warrants it, then we can talk about doing
fulcrum-dev list at some point.  Just do [fulcrum] in the subject if we want
to setup a pattern for filterning turbine versus fulcrum email.

I like the groovy one, it seems pretty straightforward.  I would be
interested in hearing more disucssion on ResourceManager.   IN some ways it
overlaps with with how we might use commons-configuration.  Also Turbine has
a similar type service, well, not really a service, but has the same type of
functinality.  It may make sense to unify the two...

Also, is urn:avalon:temp a standard avalon value?  Should a temp directory
be configured on a service by service level?  I am wondering if having just
a single temp directory could cause problems?

Looking forward to all the new stuff!

Eric
