Active_fedora first try. Install, test, console tour
Jacob Larsen
Hi all
Just wanted to share my first experiences on active fedora with you. Hopefully it can be helpful to both adopters and mediashelf.
I’ve followed the documentation (http://projects.mediashelf.us/wiki/active-fedora/Documentation) online as accurate as possible.
I.m running Ubuntu 9 based linux distro (Mint).
Installing: (http://projects.mediashelf.us/wiki/active-fedora/Setting_up_Fedora_and_Solr_for_use_with_ActiveFedora)
Tried to use the Fedora/Solr Unix bundle as described in the wiki (Se link above). Gave me an old version of fedora (3.2.1) with no data In fedora, but a usable solr index.
Deleted all that.
Installed fedora 3.3 + solr 1.4 using the instructions above.
Tried to start solr, but it failed with the following error: SEVERE: org.apache.solr.common.SolrException: Error loading class 'schema.UnicodeNormalizationFilterFactory'
Changed $FEDORA_HOME/solr/conf/solrconf.xml <abortOnConfigurationError>${solr.abortOnConfigurationError:false}</abortOnConfigurationError> from “true” to “false”.
Sorl + fedora now works (But I guess there may still be Unicode errors in the solr index???)
Getting gems, code and dependencies
I guess active_fedora has two repositories at the moment. The BitBucket as described on the wiki, and one at Github. I chose the first one. No problems so afar.
Dependencies gave a few problems. First I needed some extra ruby libraries, that Ubuntu didn’t have:
sudo apt-get install libopenssl-ruby
sudo apt-get install ruby1.8-dev
sudo apt-get install irb
uby
I also needed the following gems
activeresource (2.3.5)
hoe (2.6.0) (1.11 as described in the wiki made the test fail)
Then “rake spec” passed 65 of 66 tests – I took that for OK
Console tour http://projects.mediashelf.us/wiki/active-fedora/ActiveFedora_Console_Tour:
Really good tutorial. But actually a little hard to find. Please consider rename it to “getting started” or “tutorial” etc.
The “tour” went fine. Only small error is in the “Finding Objects” section.
solr_result = ActiveFedora::SolrService.instance.conn.query('conforms_to_field:info\:fedora/afmodel\:OralHistory') did’t work for me. A little look at the index (through luke (http://www.getopt.org/luke/)) helped me to change the query to:
solr_result = ActiveFedora::SolrService.instance.conn.query('active_fedora_model_s:info\:fedora/afmodel\:OralHistory')
Also the Base.find(:all) didn’t work for me. Failed with: NameError: uninitialized constant Base.
Allover impression.
General there are some references to old software versions. Everything seems to work fine with new versions – but it looks from the wiki like the project is old and isn’t maintained.
This took me half a day, and it was indeed worth it. Hope that others can do this exercise, a little faster with my hints.
I’ll keep familiarize myself with ruby/rails/fedora through Active Fedora and will keep posting my experiences.
I will look forward to a beta version of Hydrenga.
Thanks
Jacob

Great Matt
Btw. I have also installed hydrangea following http://github.com/projecthydra/hydrangea/blob/master/README.textile and http://docs.google.com/View?id=ddrmhvjh_181gj9b7rcv and it worked fine. I have a clean hydrangea installation running.
I am now ready to start coding myself.
