Greta de Groat researched and wrote the report, which was sponsored by DLF Aquifer and funded by the Gladys Krieble Delmas Foundation.
The report is organized according to user tasks and services, and what metadata would be needed to support those tasks and services.
From the executive summary, "Tools were evaluated for general applicability across digital library and other cultural heritage environments. The results of the research show that a handful of tools are usable as-is, but many tools need more work to be generally applicable in a variety of environments."
The report may be of interest to digital library developers and project managers as well as metadata specialists in cultural heritage organizations.
The report is now available as a PDF from the DLF website at http://www.diglib.org/aquifer/dlf110.pdf. A print version will also be available for purchase soon.

The MODS and Asset Actions Explorer is an experimental web service that allows anyone to upload MODS XML files, including modsCollection files, and verify that uploaded MODS records comply with the MODS XML Schema and also to check the uploaded records against the MODS Levels of Adoption Guidelines. In addition to MODS records, the service also allows the upload of Asset Action Packages which is another experimental format being developed by the DLF Aquifer project. An Asset Action Package is an XML file containing a defined set of actionable URIs for a digital resource that delivers named, typed actions for that resource.
Anyone is welcome to get an account and upload their MODS records for validation and checking.

The model DLF is experimenting with is something like an IPO process. An Aquifer "prospectus" describes the active elements of the initiative and offers suggested business models for sustainability and future development. Interested parties are invited to submit responses to a survey, indicating their interest in taking on responsibility for the American Social History Online Web site, or other elements of Aquifer that fit with their organization's mission. DLF will host a community meeting and q&a for prospective new hosts, and to discover which elements of the Aquifer initiative DLF members would like to keep active within the Digital Library Federation. The community meeting will be held at DLF Fall Forum 2008 in Providence, R.I. in November.
More information about Aquifer and American Social History Online is available on the project wiki.

Speaking of Jenn, she and several members of the metadata working group, John Chapman, Sarah Shreeves, Laura Akerman, and Bill Landis have had their article, "Promoting shareability: Metadata activities of the DLF Aquifer initiative" accepted for publication in the Journal of Library Metadata. Look for it in the next issue. Congratulations--and thanks for a job well done!

Browse through collections to see what is new, including contributions from Columbia and Northwestern. Try a simple search on "immigration" or "railroads" to see what combining these rich collections from different libraries offers. It is not too late to submit collections to be included in the next update! Consult the "about" page on the American Social History Online Web site to find out how.

Follow the assessment process as it develops at Deborah Holmes-Wong's poster session at the American Library Association meeting in Anaheim, CA, Saturday, June 28, 2008, 11:00 am – 12:30 pm and at the Library Assessment Conference in Seattle, where I will review all the elements that have gone into keeping the project focused on the user in a talk on August 5th. In the mean time, follow the assessment process as it unfolds on the Services Working Group public wiki. Comments and questions are welcome.

Several people twittered about asset actions during the BoF. People are beginning to see what kinds of services can be enabled if asset actions are available and were interested in asset actions as an implementation of OAI-ORE. It might be interesting to experiment with generating asset actions as a service for data providers, making them available for harvesting so they could be deployed in the local environment as well as the aggregation.
The panel on agile development sparked some comments too. People were especially enthusiastic about the Google maps mashup on the development server that will go live in a few weeks. The Technical Advisory Group that keeps us on track congratulated the team for scoping the project in a way that allowed us to develop useful and interesting services. It was a good meeting, despite the snow flurries early in the week!

As I type this, a task which was previously throwing seg faults has been running for about 30 minutes without error, so my hope is that all this trouble has at least solved that problem.

- Make sure libxml-ruby is working. See my previous blog post on installing it for Windows.
- 'gem install ruby-xslt' this downloads the gem and attempts to compile and install. It fails, but it leaves all the files in your ruby\lib\...\gems folder. I got 0.9.5 version of ruby-xslt
- Download the latest versions of libxml2, libxslt, and libiconv with all the binaries, includes, and libs for Windows. I copied the *.dll files into my windows\system32 folder.
- Now the trial and error began. I had to tweak the Makefile to get the include and lib paths correct for my system.
- I was using the MS Visual Studio (VS) tools NMAKE and CL. A major issue was the version of these tools. I started off with the VS 2005, but discovered that it links to a different version of the C runtime that is not compatible with the dependent DLLs, like libxml2.dll, etc. I had to install VS 6.0, and this seemed to solve the problem.
- Next I needed to make some modifications to the xslt_lib.c file. It seemed to be using some non-ANSI C constructs that MS C compiler didn't like. These seemed to be C99 compliant stuff like dynamically allocated arrays, but apparently VS does not support C99.
- Finally, got a compiled and linked version that works. Since by this time I didn't feel like messing with gem install scripts, I just manually moved all the files into their normal ruby directories.
- xslt_lib.so => \ruby\lib\ruby\site_ruby\1.8\i386-msvcrt\xml folder
- xslt.rb => \ruby\lib\ruby\site_ruby\1.8\xml
