Convert 647

[kirkhess]

While this is generally used for FAST headings and not used with LCSH, LC should have these in their catalog through CONSER and the structure is the same as a 648 FAST heading which is supported.

Probably just adding '647' here will work. https://github.com/lcnetdev/marc2bibframe2/blob/master/xsl/ConvSpec-600-662.xsl#L552C45-L552C45

Can you point us to a sample record, please? Preferably one that contains a FAST id.

There's about 7k CONSER records with 647 (although many are not held by LC) - here's one

https://lccn.loc.gov/2004205749/marcxml aka ocn 54481706

<datafield ind1=" " ind2="7" tag="647">
    <subfield code="a">Allied Occupation of Germany</subfield>
    <subfield code="c">(Germany :</subfield>
    <subfield code="d">1918-1930)</subfield>
    <subfield code="2">fast</subfield>
    <subfield code="0">(OCoLC)fst01351651</subfield>
    <subfield code="1">https://id.oclc.org/worldcat/entity/E39Qhp4vB9x3k8H8xR7TqHFkBX</subfield>
</datafield>

We're adding $1 to 647s to point to WC entities, eg. ocn 368128017

        <datafield tag="647" ind1=" " ind2="7">
          <subfield code="a">American Revolution</subfield>
          <subfield code="c">(United States :</subfield>
          <subfield code="d">1775-1783)</subfield>
          <subfield code="2">fast</subfield>
          <subfield code="0">(OCoLC)fst01351668</subfield>
          <subfield code="1">https://id.oclc.org/worldcat/entity/E39Qhp4vB989PWKg6VGKmH6MwK</subfield>
    </datafield>

In that case, the $1 is a wco:Event, so something like this:

<bf:subject>
    <wco:Event rdf:about="https://id.oclc.org/worldcat/entity/E39Qhp4vB989PWKg6VGKmH6MwK">
        <rdfs:label>American Revolution (United States : 1775-1783)</rdfs:label>
        <bf:identifiedBy>
            <bf:Local>
                <rdf:value>fst01351668</rdf:value>
                <rdfs:label>(OCoLC)fst01351668</rdfs:label>
                <bf:source>
                    <bf:Source>
                        <rdf:value>OCoLC</rdf:value>
                    </bf:Source>
                </bf:source>
            </bf:Local>
        </bf:identifiedBy>
        <bf:source>
            <bf:Source bf:about="http://id.loc.gov/vocabulary/subjectSchemes/fast"/>
        </bf:source>
    </wco:Event>
</bf:subject>

wco:Event probably is a close match to bf:Event, although the proposed Event model is somewhat different (and untested...)
