Eric, if you want to leap into the linked data world in the fastest,
easiest way possible, then I suggest looking at microdata markup, e.g.
schema.org.[1] Schema.org does not require you to transform your data at
all: it only requires mark-up of your online displays. This makes sense
because as long as your data is in local databases, it's not visible to
the linked data universe anyway; so why not take the easy way out and
just add linked data to your public online displays? This doesn't
require a transformation of your entire record (some of which may not be
suitable as linked data in any case), only those "things" that are
likely to link usefully. This latter generally means "things for which
you have an identifier." And you make no changes to your database, only
to display.
OCLC is already producing this markup in WorldCat records [2]-- not
perfectly, of course, lots of warts, but it is a first step. However, it
is a first step that makes more sense to me than *transforming* or
*cross-walking* current metadata. It also, I believe, will help us
understand what bits of our current metadata will make the transition to
linked data, and what bits should remain as accessible documents that
users can reach through linked data.

[1] http://schema.org, and look at the work going on to add
bibliographic properties at
http://www.w3.org/community/schemabibex/wiki/Main_Page
[2] look at the "linked data" section of any WorldCat page for a single
item, such
ashttp://www.worldcat.org/title/selection-of-early-statistical-papers-of-j-neyman/oclc/527725&referer=brief_results

Eric, I think this skips a step - which is the design step in which you
create a domain model that uses linked data as its basis. RDF is not a
serialization; it actually may require you to re-think the basic
structure of your metadata. The reason for that is that it provides
capabilities that record-based data models do not. Rather than starting
with current metadata, you need to take a step back and ask: what does
my information world look like as linked data?
I respectfully disagree. I do not think it necessary to create a domain model
ahead of time; I do not think it is necessary for us to re-think our metadata
structures. There already exists tools enabling us — cultural heritage
institutions — to manifest our metadata as RDF. The manifestations may not be
perfect, but “we need to learn to walk before we run” and the metadata
structures we have right now will work for right now. As we mature we can
refine our processes. I do not advocate “stepping back and asking”. I advocate
looking forward and doing. —Eric Morgan
