  • Metaphor, picturesque
  • Provenance metadata
  • Dear Mr. Horvath,
    Thanks, the links do work now. Nice work!
    We matched our records to the LCSH in a different project (called "MACS") a while ago. The
    result of the project was a database of corresponding entries in our SWD, the LCHS and
    RAMEAU. So we did not solve that problem in our linked data project but simply used the
    information already available. Unfortunately, the URIs are not included, but it was
    possible to derive them from the IDs used (easy for LCSH, hard for RAMEAU).
    I am not sure if these mappings are freely available, but if you are interested, I could
    try to find out. A typical mapping looks like this:
    <?xml version="1.0" encoding="UTF-8"?>
    <!-- Contents from database Work -->
    ...
    <add>
    <doc>
    <field name="id">MACS0000001</field>
    <field name="SWD">Schauspielkunst</field>
    <field name="SWD_number">4129090-2</field>
    <field name="RAMEAU">Art dramatique</field>
    <field name="RAMEAU_number">FRBNF11930966X</field>
    <field name="LCSH">Acting</field>
    <field name="LCSH_number">sh 85000691</field>
    </doc>
    ...
    </add>
    Would that be at all useful to you?

  • By the way, Adam, I'd also like to seize the opportunity to invite you to consider
    participation this Library Linked Data effort. Your library has done work of premium
    importance for the field, it would be interesting to have you around.

  • Dear Mr. Horvath,
    Thanks, the links do work now. Nice work!
    We matched our records to the LCSH in a different project (called "MACS") a while ago. The
    result of the project was a database of corresponding entries in our SWD, the LCHS and
    RAMEAU. So we did not solve that problem in our linked data project but simply used the
    information already available. Unfortunately, the URIs are not included, but it was
    possible to derive them from the IDs used (easy for LCSH, hard for RAMEAU).
    I am not sure if these mappings are freely available, but if you are interested, I could
    try to find out. A typical mapping looks like this:
    <?xml version="1.0" encoding="UTF-8"?>
    <!-- Contents from database Work -->
