Nathan,

I gave a presentation on the TRLN project that Jason previously referred to at SAA this past year. 

Here is a link to my ppt, which includes some basic diagrams of the system architecture and some screenshots of the user interface:

You might find the speaker notes helpful as well.  In brief, we are merging EAD records and MARC records for the same collection into a third hybrid record that is indexed in our discovery layer (Endeca).  The hybrid record includes the entire container list or <dsc> section.

I have a follow up question to those with OPAC's that index EAD (minus Eric as he already explained).  How deep does the EAD indexing go?  Is only collection level information scrapped or can users search directly into container lists from the general OPAC?

Harvard's indexes the full finding aid.


Okay one more, how does the OPAC interact with the EAD xml files?  Is EAD information scrapped (EAD header?  Collection level <did>?) and a MARC record generated or does the index work directly with the XML?

The collection-level MARC record and the finding aids both exist.  In the opac, there is a link right below the title for "more about this collection" that opens the full finding aid.

An example: http://holliscatalog.harvard.edu/?itemid=|library/m/aleph|009516273
Click on <<more about this collection>> to see the finding aid with links to digitized contents
To get back to the bib. record, click on "Standard view"


Thanks again!

Nathan

Just out of curiosity, is anyone using an online catalog that is entirely EAD-based?  I know many institutions catalog monographs and other items more suitable for MARC, but not everyone might.  It's certainly possible and an interesting idea.

On the flip side, does anyone's traditional online catalog index EAD as well as MARC?  Maybe a federated search of some sort.  Seems like I remember seeing one.

Happy Friday!
