Re: [Standards-general] Re: [Collections-group] metadata for


I'm forwarding an email interchange regarding NSDL metadata. The conversation was spawned by a reference to an IEEE standard for software metadata called BIDM (basic interoperability data model.) Up to now THREDDS has not concerned itself with this sort of metadata, but perhaps we should consider it because a significant element of THREDDS is to provide software for accessing and analyzing scientific data.

Shirley, the NSDL team at Cornell (through Diane) are making such crosswalks
and pointers to such crosswalks available to various communities at large.
So once such  cross-walks are complete, they can be "published" for wide use
thus promoting interoperability..

Looks like we'll need to do a crosswalk for the BIDM to the Dublin Core
anyway for our project, so we can make it available to anyone who wants
to use it.

Susan, Mimi, et al.:

I've taken the liberty of copying this comment to the standards-general
list, in hopes of bringing in some of the metadata-aware folks on that
into this conversation.

I found Susan's reply very interesting and took a look at the links she
suggested, which seemed perfectly relevant to the question posed.  One
concern I had was that Mimi's question ended with the phrase, " ... in the

NSDL context," and I wanted to attempt a bit of an addendum to Susan's
answer based on some concerns I see buried in this exchange.

While the metadata options Susan mentions may be a good fit for Mimi's
collection, this does not necessarily mean that it is automatically so "in

the NSDL context." NSDL will be built based on a metadata repository
expecting to process a limited number of metadata formats (I refer
to the recently published paper in DLIB Magazine for more details: ). In order to assure
that the metadata that Mimi's project creates can be exposed to potential
users via the NSDL, there needs to be some planning, somewhere, to make
sure that there is a way to crosswalk the metadata into the NSDL metadata
lingua franca (Dublin Core).  Choosing a standard format, as Susan has
suggested, makes far more long-term sense than making something up, and I
commend Mimi for going the extra mile to find a standard that suits her

On the other hand, the BIDM is not now one of the standard formats that
NSDL is expecting to process routinely (information on those formats is at

the NSDL Metadata Resources Page, at: ).  Does that mean that
Mimi shouldn't use it? No, but it means that Mimi, or anyone else using a
format not already listed needs to make some extra efforts to make sure
that the format they're using "natively" will be usable as well by the
Metadata Repository, preferably BEFORE it comes time to import their
records into the repository.  How to do that?  My suggestions are as

1. Get in contact with the body maintaining the standards, and see if they

already have a crosswalk to Dublin Core;
2. If they don't, suggest that it would be really great if they could
create and support one.  Tell them why;
3. If they won't, find some other users and see if anyone has already done

a crosswalk;
4. If they haven't, let the metadata mavens on the Standards and Metadata
Workspace know that you need some help (preferably via the
Standards-general mailing list: standards-general@xxxxxxxxxxxxxxxxxxxxx)

Keep in mind that the CI group at Cornell, currently engaged in building
the Metadata Repository and associated software and processes, has a
full plate right now, and any efforts you make towards a recognizable
metadata format with an already existing DC crosswalk will pay off, big
time, for us all.
