object analysis • three content files: high bit rate MPEG4, low bit rate QuickTime, and TEI text transcription • how many manifestations are we dealing with? • what’s the intended use? • is there innate structure to manifestations? • do we want to present that structure? • what do we need to manage this object? • what do we need to let users find this?
extension schema • descriptive metadata • administrative metadata • technical • rights • digital provenance • source • XLink
root <mets> element • attributes: OBJID, LABEL, TYPE, PROFILE • namespace declarations • schemaLocation declaration
building the file section • file grouping • file specific technical metadata • internal vs. external files • file location mechanisms • welcome to XML namespacing • the GROUPID attribute
building the structural map • <div> structures • content file affordances • plain <fptrs> vs. use of <area>/<par>/<seq> elements
building administrative metadata • internal vs. external • welcome to XML namespacing (again) • relating files to administrative metadata
building descriptive metadata • internal vs. external • relating object, files to descriptive metadata
building the <metsHdr> • why altRecordID?
a few final words of advice • validation is your friend; make sure your XML software really validates everything, including extension schema sections. • if you are creating content (say, TEI), make sure you create it in a way that makes it easy to build METS around it. • simpler is better. • METS profiles are even better friends than validation.
