I'm happy to announce that the Barton Catalog dataset, once made available and later removed is now back online. Find it at
http://simile.mit.edu/rdf-test-data/barton/ Regarding the speculations that appeared on various web sites and podcasts about OLCL complains being the reason behind us pulling the plug on the public dataset, I can officially state that this was NOT the case: the reasons where internal and have now being resolved. MIT maintains copyright of the dataset as a whole and grants a license of use that is Creative Commons Attribution-Noncommercial. As for the individual records, most of the data is factual, therefore not-copyrightable. For the non-factual data (such as, for example, subject headings), the individual cataloger and/or the institution that paid her/his salary owns the copyright of that work. If such work was performed by a US government employee (such as, for example, employees of the Library of Congress or employees of municipal libraries), the data is in the public domain. The full license, along with some disclaimers and requirements can be found at http://simile.mit.edu/rdf-test-data/barton/LICENSE.txt - o - You will notice that the dataset now contains two formats instead of the previous three: the MARC 21 version of the dataset is *not* being made public at this time because MIT considers some of that information contained in there sensitive. Would sufficient demand emerge, we might consider performing a cleanup/filtering of the MARC 21 data to make it publicly available, but for now, we release the MODS and MODS/RDF data only (which should be sufficient for both RDF triple-store testing needs and for open OPAC usages). - o - We would also suggest people to avoid mirroring and/or bittorrenting of these files: we would much rather trade bandwidth for more realistic download stats of the data (which we are committed to make publicly available). If you make any use of this data, please let us know. Thanks for your patience and enjoy our 1 million records (~50 million RDF statements)! -- Stefano Mazzocchi Digital Libraries Research Group Research Scientist Massachusetts Institute of Technology E25-131, 77 Massachusetts Ave skype: stefanomazzocchi Cambridge, MA 02139-4307, USA email: stefanom at mit . edu ------------------------------------------------------------------- _______________________________________________ General mailing list [email protected] http://simile.mit.edu/mailman/listinfo/general
