17: metadata_convert.pl - prototype metadata conversion for NSDL-LONCAPA gateway
18:
19: =head1 SYNOPSIS
20:
21: Usage: perl metadata_convert.pl
22:
23: There is no input to this script. The output of this script
24: will describe the success or failure of the metadata conversion that happens.
25:
26: The script is organized into the following sections:

46: =head1 DESCRIPTION
47:
48: This script converts LON-CAPA metadata into NSDL metadata
49: and converts NSDL metadata into LON-CAPA metadata.
50:
51: Example metadata strings are included in this prototype
52: script--they are named by variables such as
53: I<$LONCAPA_metadata> and I<$NSDL_metadata>.
54:
55: The XML-processing "engine" for the transformation is B<XML::Xalan>
56: available at http://search.cpan.org/search?dist=XML-Xalan. This engine
57: takes in XML files of one DTD type and converts them into XML
58: files of another DTD type according to stylesheets.
59:
60: alpha.xml alpha_to_beta.xsl beta.xml
61: (alpha.dtd) ----------------> (beta.dtd)
62:
63: LON-CAPA metadata currently consists of 13 different metadata fields
64: (with defined datatypes):
65: abstract, author, copyright, creationdate, dependencies, keywords, language,
66: lastrevisiondate, mime, notes, owner, subject, and title.
67:
68: For purposes of the gateway implementation, I am defining a qualified LON-CAPA
69: metadata to consist of additional fields (which can be automatically
70: generated from information on the LON-CAPA network):
71:
72: "uri", which is both the address and unique identifier of the educational
73: resource from the standpoint of LON-CAPA.
74:
75: "structure", which is derived from the LON-CAPA MIME type of the file
76:
77: "aggregation", which is derived from the LON-CAPA MIME type of the file
78:
79: "bytesize", the size of the LON-CAPA resource in bytes (octets)
80:
81: "version", which comes from information accessed from the LON-CAPA network
82:
83: "metauri", which comes from the uri (with .meta appended)
84:
85: In the future, more LON-CAPA metadata fields are expected to be added, and
86: it may also be that several of the fields change, or are removed.
87:
88: The current viewpoint regarding NSDL is to support unqualified dublin
89: core and IEEE LOM, with IEEE LOM being preferred. Both are to be
90: supported (dublin core being the minimal and IEEE LOM being the maximal).
91: There are 15 unqualified
92: Dublin Core elements. For version 6.4 of IEEE LOM (March 4, 2002--this is
93: the version the gateway approach is based off of) there are 77 IEEE LOM
94: category names with 58 IEEE LOM fields which correspond to a subset of
95: the 77 category names. A complete description of IEEE LOM version 6.4
96: is available at http://ltsc.ieee.org/doc/wg12/LOM_WD6_4.pdf. Note that
97: the 15 Dublin Core elements correspond to a subset of the 58 IEEE LOM fields.
98:
99: A summary (for the sake of brevity, with some details omitted) of how
100: IEEE LOM and Dublin Core and LON-CAPA interrelate is described below
101: (column order=LON-CAPA field, IEEE LOM datatype, IEEE LOM field,
102: and Dublin Core Field).
103: Note that an asterisk (*) for the LON-CAPA field indicates that a IEEE
104: LOM field value can probably be generated for
105: the LON-CAPA to NSDL metadata transformation. Note that a question mark (?)
106: indicates that a LOM field value may in the future be generated for
107: the transformation. Note that a minus sign (-) indicates that a LOM
108: field value may not be generated for the transformation in the foreseeable
109: future (never say absolutely never though). The mappings below are not
110: perfectly bidirectional; there are a number of one-to-many and many-to-one
111: mappings that are involved in the metadata conversion.
