As part of the DFT group I'm wondering of the MIG has any definition(s) of metadata to propose that would be useful for out efforts to define things and your interests.
As context we have had some working defintions a bit of which was disucssed at P3.
We start very generally with "Metadata is a type of data object that that contains attributes describing properties of an associated data or digital object. The association between a data object and metadata is that the content of the metadata describes the data object. "
Since metadata plays different roles for different functions we added some additional ideas such as a role in PIDs.
" It may contain as key the persistent identifier of that associated object. "......but things get a little complicated as we note that metadata (MD) may serve different purposes, such as helping people to find data of relevance - discovery (Michener 2006) or to bring data together –a federation role.
And wecan note many other roles:
(aiding in) Discovery, Access, providing context, Selection, Licensing, authorization, Quality, suitability and Provenance (such as describing how data were gathered, reproducibility or summarizing terms for reuse .
Because of the different roles we may distinguish many different types of MD such as:
Administrative Metadata "Provides information about how to manage a resource,such asrights data, intellectualproperty info, date of creation and editing – can be very important for legal reasons." or
The structural organization of a data object,such as chaptersin a book,sentencesin achapter, etc,that allows usto figure out how an objectshould be puttogether. Also refers to the underlying structural metadata of digital objects that tells computers how to assemble them.
To this one may add list of MD attributes such as:
Quality & Provenance (such as describing how data were gathered, reproducibility or summarizing terms for reuse.)
When all this is taken into account, and it is just part of the story, we end up with less of a definition and more of an encylopedia entry.. But perhaps this is still useful.
