XTF and FEDORA — Comments from the Community

Some questions and observations that have come in through mechanisms other than blog comments on the analysis of the XTF/FEDORA integration. I’ve reproduced those here for the sake of completeness, but also be sure to go back to the first two entries in this series to read the comments there as well.

Indiana University’s Observations

As it turns out, Indiana University is considering much the same path. They have an existing FEDORA-based repository and a number of XTF projects that have been in development for a while. They, too, are looking to put these two technologies together and have a page on their project website with Digital Repository Architecture > Search”>IU’s observations of an XTF plus FEDORA (plus more!) combination.

Analysis of CDL’s XTF textIndexer to Replace the Local Files with FEDORA Objects

This is a continuation of the investigation about integrating the California Digital Library’s XTF software into the FEDORA digital object repository that started earlier. This analysis looks at the textIndexer module in particular, starting with an overview of how textIndexer works now with filesystem-based objects and ending with an outline of how this could with reading objects from a FEDORA repository instead.

XTF’s Native File System handler

Natively, XTF wants to read content out of the file system. The core of the processing is done in these two class files:


CDL’s XTF as a Front End to Fedora

We’re experimenting pretty heavily now with the California Digital Library‘s XTF framework as a front-end to a FEDORA object repository. Initial efforts look promising — thanks go out to Brian Tingle and Kirk Hastings of CDL; Jeff Cousens, Steve DiDomenico, and Bill Parod from Northwestern; and Ross Wayland from UVa for helping us along in the right direction.

XTF into Eclipse How-To

As we get more serious about XTF, I wrote up a How-To document for bringing XTF into Eclipse so that it can be deployed as a dynamic web application. Let me know if you find it useful. Definitely let me know if you find it in error. We haven’t put a version of XTF into OhioLINK’s source code repository, but that might follow shortly.
