A question about the MARC to MODS mapping, and a typo in the User Guidelines: In the MARC to MODS mapping for physicalDescription, the 007/13 (values a,p,r) is used for to determine reformatingQuality. Should the mapping also check that the 007/00 is "c" (electronic resource)? Someone might crosswalk a record for a sound recording or motion picture, which also use a, p, and/or r in the 007/13. Or maybe that's out of scope? There are some typos in the User Guidelines where the MODS namespace is given. The MODS v.3 schema uses the namespace URL: <xsd:schema targetNamespace="http://www.loc.gov/mods/v3" ...> The XML Structures section of the User Guidelines says: <mods xmlns:mods: "http://www.loc.gov/standards/mods/3"> The namespace URLs in the UG should match the namespace in the schema, I think. There's also a syntax typo, should be xmlns:mods="...". The second example has the same typos. It may also be useful to include the schemaLocation in the UG (though it is already in the examples). -- Tod A. Olson <[log in to unmask]> "How do you know I'm mad?" said Alice.
