This stylesheet transforms MODS version 3.2 records and collections of records to simple Dublin Core (DC) records, based on the Library of Congress' MODS to simple DC mapping Revision 1.1 (2007-05-18)  <http://www.loc.gov/standards/mods/mods-dcsimple.html> 

It was revised by Priscilla Caplan 10/23/2013 to include the following changes:

1) For  mods:subject elements with any of the following subelements: <topic>, <geographic>, <temporal>, <genre>, create a dc:subject by concatenating the values of each subelement in mods:subject in the order that they occur, separated by dash-dash  For all mods:geographic within a single mods:subject create a dc:coverage with their values, separated by dash-dash.  For each mods:temporal create a dc:coverage with that value.

2) For the first occurence of the <date> subelement <dateCreated>, create dc:date with the value of dateCreated.  (There should be zero or one dateCreated.)  If there is no subelement <dateCreated> and there is a subelement <dateIssued>, create dc:date with the value of <dateIssued>.  If there are no subelements <dateIssued> or <dateCreated> but there is a subelement <copyrightDate>, create dc:date with the value of copyrightDate.  If there are no subelements <dateIssued>, <dateCreated> or <copyrightDate> but there is a subelement <dateOther>, create dc:date with the value of <dateOther>.

3) If there is a <date> subelement <dateIssued> and also a subelement <dateCreated>, create dc:description with the value of <dateCreated> prefaced by "Creation date: ".  E.g. if MODS contains <originInfo><dateIssued>2012</dateIssued><dateCreated>2011</dateCreated></originInfo> create DC <date>2012</date><description>Creation date: 2011</description.

4) If there is a <date> subelement <dateIssued> or <dateCreated> and also a subelement <copyrightDate>, create a dc:description with the value of <copyrightDate> prefaced by "Copyright date: ".

5) For each <date> sublement <dateCaptured>, <dateValid> and <dateModified>, create dc:description with the valude of the subelement preceded by the label "Capture date: ", "Date valid: ", and/or "Modification date: " respectively.

6) If MODS contains both <originInfo> subelements <place> and <publisher>, format dc:publisher with the value of <place>, space, colon, space, value of <publisher>.  E.g. MODS <place>Boston</place><publisher>Harper & Row</publisher> create DC <publisher>Boston : Harper & Row</publisher>. 

7)  If MODS contains only <publisher> and not <place>, format dc:publisher with the value of <publisher>.

8) If MODS contains only <place> and not <publisher>, format dc:description with the value of <place> preceded by "Place of publication: ".

9) If MODS contains the subelement <frequency>, format dc:description with the value of <frequency> preceded by "Frequency: ".

10) Do not create dc:format for the subelement <internetMediaType>.

11) If there is a type attribute to <identifier> put the type attribute in parens before the identifier value, e.g. <identifier>(ISSN) 2431-2938</identifier>.

12) If there is a <url> subelement in <location>, put the value into dc:identifier preceded by "(URL)".  The LC xslt maps <url> to dc:identifier but does not supply the prefix.
