Hello Ben 1. A ResourceAttribueFinderModule sounds like the way to go here -- how do you envisage the policies looking to make use of this? Also it might be worth looking at some of the FeSL code -- not sure if you are intending this as part of FeSL or the existing Fedora XACML functionality (or

Aaron-- You don't have to convince me of the dangers. I have ugly memories of watching Ross Wayland and Thorny Staples being chafed by the straightjacket of strong integrity for objects/bdefs/bmechs that was baked into the 2.x series. {grin} With time, though, I've forgotten the grim images eno

All the tests except the CommandLineUtilities test work. I have the appropriate pathnames in the windows variable. But the instalation of fedora 3.3 didnot gave me the fedora-modify-control-group utility whose usage is mentioned in https://wiki.duraspace.org/display/FCR30/Command-Line+Utilities

Interesting bit of history, Aaron. I agree with Adam, but in light of the reasons you list, I can see the virtues of the current design. In which case, it may make more sense to realistically set user expectations up front and make these principles explicit in the documentation, then provide

While not really disagreeing with this take, I would point out that permitting the successful ingestion of what is presumed by the user to be a content model (but which lacks the crucial triple) which is then discovered not to function as a content model could also be surprising. The CMA is such

I agree with Adam -- verifying that objects are bound to valid Content Models before attempting to run their disseminations is another useful mechanism to maintain referential integrity among Fedora objects, not just at ingest time, but also after updates. -- Scott aj...@virginia.edu wrote: >

Since one would rather not put any unnecessary burden on people, I'm inclined to suggest cautiously that the defaulting functionality be left in. Anyone who is directly creating a content model (instead of using a wizard interface) will probably be aware of the need for correct RDF and comfortab

Just one thing to add re the autogeneration of a "default" content model assertion - we do currently do this for Fedora objects that don't have a RELS-EXT datastream or don't specify a content model in RELS-EXT. So maybe we should also remove this functionality? > -Original Message- > Fro

Hello Steve and Fedora group, Thanky you for your fast response.This sure seems like much better approach, no so much RAM consuming. What bothers me is the fact I don't know how to reference datastreams on file system. With use of API-M I know I can ingest with POST method via http like: http:/
