From my days (many moons ago) as a mining geologist and later as
GIS (Geographical Information Services) developer, people have
consistently overlooked the two main costs/problems associated
with metadata/databases.
a) Assigning the object/data attributes for classification that
are relevant
b) Verification that the assigned attributes are
correct/rational AND that the were entered into the data base
correctly.
When Cities/States/Government Agencies were assigning their
budgets for major GIS projects the general rule was:
10% for Hardware/Software
30% for data acquisition and classification
60% for validation the data was both classified correctly and
entered correctly
Without the validation that the metadata is correct, the whole
database becomes basically untrustworthy and may even become
actionable by end users.

To use any format/standard would (and always* will) require
manual metadata

some of the
most basic metadata can't be inferred by the content at all.
Metadata standards are a Good Thing, but the lack of standards hasn't
prevented anyone from doing searchable video databases of Salsa moves.
After all, it's been possible to do this since you could hook a Mac Plus
up to videodisc player. It's just that nobody** cares.
