In IT world, there is such framework as "Enterprise Architecture (EA)"
and our government appears to be very interested in that concept.
http://www.fcw.com/fcw/articles/2003/0203/web-fea-02-04-03.asp
If you visit OMB website, you can find that their EA comprises of five
reference models -- PRM, BRM, SRM, TRM, and DRM.
I am looking for actual collaterals of DRM. The purpose is to obtain
concrete idea of what DRM is in practice. I know OMB has not released
federal government-wide DRM, so I am looking for other examples of DRM
or DRM-equivalent.
Links to actural collateral is ideal, with explanation or case study
even better. If not, tell me assured way to obtain one. I do not
know what collateral DRM development usually produces, but my guess is
that they include diagrams such as ER, IDEF, UML.
Please look in the federal agencies first, but states or industry
examples are okay, too. |

Can you define what you mean by "collaterals of DRM?" The term
appears nowhere in the net.
Thank you,

Hello brisktea-ga,
Interesting question. And as I'm sure you know, an elusive one, given
the very early stage of DRM development.
One of the most detailed documents I came across regarding DRM
architecture can be seen here:
http://www.dtic.mil/cendi/presentations/xml_christian_4_30_03.ppt
Please look it over and tell me if this is the type of case study you
are looking for. If it is, I can probably locate several similar
types of studies/presentations.
If not, any additional information you can provide about what,
precisely, you need would help researchers to focus their
investigation.
Thanks.

brisktea,
Please let me know if the following documents are useful to you:
"Information and Data Reference Model (DRM): Standards Based
Architecture to Support Federated Data Management
http://216.239.53.104/search?q=cache:BeZEvKgW8xYJ:www.ichnet.org/Federated%2520Data%2520Management.doc+%22data+reference+models%22+in+use&hl=en&ie=UTF-8
* There are some "cases" mentioned in Appendix A that may be helpful.

Here is the PDF version of the paper I referenced, and which I realize
Pafalafa linked to in a PowerPoint presentation. (I was uanable to
open the PPT file last night, so did not know that we had uncovered
the same title!)

Thank you jbf777, pafalafa, and umiat.
And sorry, I misconfigured my account, and was not aware of your
comments.
Since it seems that none of us know what DRM development efforts
produce, let me define that, for the sake of this question, that:
A "DRM document (=collateral)" must include a diagram such as ER,
IDEF, or UML, in order to describe the data architecture of an
enterprise.
(I don't think I'm too far off.)
So please find me some Enterprise Architecture document that contains
(or is entirely) ER, IDEF, or UML.
Thanks!

Hello brisktea,
I suspect this question may have to proceed through several rounds of
clarifications in order for the researchers to fully understand how to
best meet your needs.
Two very detailed documents on DRM have already been referenced for
you.
The first, prepared by the Industrial Advisory Group of the American
Council for Technology, is here:
http://www.iaconline.org/documents_presentations/2003/030528_IAC_EA_SIG_Information_and_Data_Reference_Model_Body.pdf
and a DRM model prepared for the military is here:
http://www.dtic.mil/cendi/presentations/xml_christian_4_30_03.ppt
These documents suggest that DRM architecture is moving "beyond" UML
and related tools into a new generation of standards. For instance,
the IAC document reports:
-----------------
The modeling architecture we propose is based on standards from the
Object
Management Group (OMG), which promulgated CORBA and UML ten years ago
and is now concentrating on metadata management and modeling
standards.
Currently OMG is articulating an overarching theme named Model Driven
Architecture, which leverages past success in modeling and middleware
standards
and incorporates some newer specifications regarding metadata
management.
Four years ago this consortium created the Meta Object Facility, a
specification for managing metadata for any sort of system within a
single framework, the core of this architecture is a modeling
framework derived from UML and now based on MOF.
A second important standard defined by OMG is XMI, XML Metadata
Interchange, which specifies the manner in which metadata can be
exchanged
between systems and tools. A critical feature of XMI is that is
carries a metamodel description along with the metadata.
--------------
The report then goes on to give examples of usinging these newer
standards.
If these reports are NOT the type of "collateral" you need, perhaps
you can tell us in what way they fall short, and what type of
additional detail you would need to have a satisfactory answer to your
question.
Any additional information you can provide would be most helpful in
getting you the best answer possible.
Thanks,
pafalafa-ga

Hello brisktea-ga,
Just wanted to check in and see if you're still interested in further
research on this question. If you are, please see the comment I made
a few days back, and let us know how you would like to proceed.
Thanks.

Thank you pafalafa,
I'm still trying to digest the series of comments posted here, but it
seems that what I'm really looking for is DM rather than DRM.
I found two examples myself:
- DOD CD Data Models in DISA website
- USDA Enterprise Data Model in USDA website
I will:
1. Digest your comments and revise my question.
2. Research on my own to see how hard it is to find what I'm looking
for.
3. Seek help here, as necessary, by creating a new question.
Thank you for your comments, and sorry for your trouble.
