[CODE4LIB] Names Added to ID.LOC.GOV
Announcement: New Vocabulary Data Added to LC Authorities and Vocabularies Service The Library of Congress is pleased to make available additional vocabularies from its Authorities and Vocabularies web service (ID.LOC.GOV), which provides access to Library of Congress standards and vocabularies as Linked Data. The new dataset is: * Library of Congress Name Authority File (LC/NAF) In addition, the service has been enhanced to provide separate access to the following datasets which have been a part of the LCSH dataset access: * Library of Congress Genre/Form Terms * Library of Congress Children's Headings The LC/NAF data are published in RDF using the MADS/RDF and SKOS/RDF vocabularies, as are the other datasets. Individual concepts are accessible at the ID.LOC.GOV web service via a web browser interface or programmatically via content-negotiation. The vocabulary data are available for bulk download in MADS and SKOS RDF (the Name file and main LCSH file will be available by Friday, August 12). **Please explore it for yourself at http://id.loc.gov. ** Contact Us about ID: As always, your feedback is important and welcomed. Though we are interested in all forms of constructive commentary on all topics related to ID, we're particularly interested in how the data available from ID.LOC.GOV is used. Your contributions directly inform service enhancements. The addition of Names has resulted in considerable changes to the ID.LOC.GOV backend. Although we have endeavored to bring the service up with all pieces in place, please be patient as we work out any remaining kinks. You can send comments or report any problems to us via the ID feedback form or ID listserv (see the web site). Background: The Authorities and Vocabularies web service was first made available in May 2009 and offered the Library of Congress Subject Headings (LCSH), the Library's initial entry into the Linked Data environment. In part by assigning each vocabulary and each data value within it a unique resource identifier (URI), the service provides a means for machines to semantically access, use, and harvest authority and vocabulary data that adheres to W3C recommendations, such as Simple Knowledge Organization System (SKOS), and the more detailed vocabulary MADS/RDF. In this way, the Authorities and Vocabularies web service also makes government data publicly and freely available in the spirit of the Open Government directive. Although the primary goal of the service is to enable machine access to Library of Congress data, a web interface serves human users searching and browsing the vocabularies. The new datasets join the term and code lists already available through the service: * Library of Congress Subject Headings (LCSH) * Thesaurus of Graphic Materials * MARC Code List for Relators * MARC Code List for Countries (which reference their equivalent ISO 3166 codes) * MARC Code List for Geographic Areas * MARC Code List for Languages (which have been cross referenced with ISO 639-1, 639-2, and 639-5, where appropriate) * PREMIS vocabularies for Cryptographic Hash Functions, Preservation Events, and Preservation Level Roles The above code lists also contain links with appropriate LCSH and LC/NAF headings. Additional vocabularies will be added in the future, including additional PREMIS controlled vocabularies. -- Kevin Ford Digital Project Coordinator Network Development MARC Standards Office Library of Congress 101 Independence Avenue, SE Washington, DC 20540-4402 Email: k...@loc.gov Tel: 202 707 3526
Re: [CODE4LIB] Names Added to ID.LOC.GOV
Thanks, Kevin. This was obviously one heck of a project! Very impressive. I looked at an entry in id.loc.gov and in VIAF and couldn't immediately see a connecting URI (browsing through the RDF/XML) -- is there one, or are there plans to create those links between the two vocabularies? Here are the records I was looking at: http://id.loc.gov/authorities/names/n84031182.html RDF: (http://id.loc.gov/authorities/names/n84031182.rdf) http://errol.oclc.org/laf/n%20%2084031182.html RDF: (http://viaf.org/viaf/69121416/rdf.xml) kc Quoting Ford, Kevin k...@loc.gov: Announcement: New Vocabulary Data Added to LC Authorities and Vocabularies Service The Library of Congress is pleased to make available additional vocabularies from its Authorities and Vocabularies web service (ID.LOC.GOV), which provides access to Library of Congress standards and vocabularies as Linked Data.

[CODE4LIB] Net::OAI::Harvester
I'm working on a Perl-based OAI harvester and have run a problem. The module that I'm using - Net::OAI::Harvester - does a great job of parsing out the different OAI tagged fields so that they can be put into a MySQL table of retrieved OAI records for searching. Unfortunately, in using the University of Michigan OAI Toolkit, I have found that at least one repository has repeated tags. In particular, multiple identifier tags. This presents a problem in that it seems that Net::OAI::Harvester gets the first (and, as far as I know how to use it, only the first) instance of a tag. In addition to the loss of data (which is always bad), it is made worse here by the fact that the repository that I'm trying to harvest usually places the URL to connect to the repository item in the second identifier tag. That being the case, the URL does not get saved to the database and the harvest is less-than-useful to our users. Does anyone know a way in which Net::OAI::Harvester can be used with oai_dc records in a way where multiple instances of a tag can be captured and then concatenated with the first one. I have spent some time trying a number of different approaches, including trying different libraries (such as XML::LibXML and XML::SAX::Parser), but I can't seem to get it to work with the input I get inside the Net::OAI::Harvester module, which has been run through the Storable module). Unfortunately, the documentation that I have been able to find on the Web does not provide information on any methods that I could use. Would it make more sense just to move to the University of Michigan Toolkit to harvest the XML records? I would prefer to continue with the Net::OAI::Harvester module if I can in that it allows me to be flexible in what sorts of schemas I'm able to harvest, not just unqualified Dublin Core. That being said, I do have one other question: Is there a way within the Net::OAI::Harvester to output the actual metadata structure that's being harvested? Thanks in advance for any assistance that you can provide! Stephen Westman

Westman, Stephen writes I'm working on a Perl-based OAI harvester and have run a problem. The module that I'm using - Net::OAI::Harvester - does a great job of parsing out the different OAI tagged fields so that they can be put into a MySQL table of retrieved OAI records for searching. I suggest you use HTTP::OAI instead. Cheers, Thomas Krichelhttp://openlib.org/home/krichel http://authorprofile.org/pkr1 skype: thomaskrichel
