Subject: [tm-pubsubj-comment] Comments on Use Case
Hi, Here are some comments about Mary's excellent Use Case posted at http://www.oasis-open.org/committees/tm-pubsubj/docs/registry- usecase.htm Mary outlines the advantages and disadvantages to using the Dublin Core Classification Schemes Advantage: These organizations have huge subject databases that can be used by those who need to classify their subject. Much work has gone into the Dublin Core by many, many experts. This would help in realizing a standard that would be acceptable to knowledge communities I think this is very important. It would be foolhardy if not impossible to attempt to duplicate these efforts. Disadvantage: Since all of these choices would be made available, it might be difficult for the publisher of the published subject to know which one is best. For example, since I am not familar with the LCC, and wouldn't know if DDC is a better choice, I would need an expert to verify that the classification I chose was the best for the subject. This would be a great responsibility on the shoulders of the experts. It may be possible to have some kind of self registration and validation. How can we depend on the validity of the subject? Are human resources available to do the validation or some validation by some online database? This would need careful consideration by the users of the resources. Another problem would be multiple entries (non unique subject identities). One person could register an LCC for "Dublin Core" as a subject while another person might want to register it as a DDC. These are very valid points. I think the project at hand is so large that we will need to build into the standard a very flexible approach that allows Topic Map creators the use of these class schemes while tolerating the possiblility that they might be misused. Valididity, over time, will derive from trustworthiness of authors and as Mary indicates there could be some sorts of validating agents. Also, we may be able to map (using a Topic Map?) subjects from one scheme to another such as the LCSH - - CANCER to the MESH --NEOPLASMS. Even this however, would be a large undertaking. In order for the Published Subjects system to be generally useful it seems to me that it will be necessary to 1) allow Topic Map creators access to the best developed general classification schemes such as those outlined in Dublin Core 2) allow them to also associate internally generated class schemes appropriate to a small community, or 3) choose not to use Published Subjects at all if the Topic Map is just for local use. Perhaps one of the decisions about how and which maps to merge may have to do with which class scheme is used and how well it maps to another class scheme--- but determining that mapping will require expertise. The alternative is the creation of a single repository with Published Subjects that some group (us?) establishes and maintains. Since I know the time and energy expended by the Library Of Congress on creating, maintining and modifying the LCSH classification system, I would not recommend this approach unless there are enormous resources available. And even if there were, it seems unlikely that a single repository would meet all of the classification needs of every Topic Map from the most specific to the most general. On another note, A feature of some of the early PSI's that I saw was the addition of some association elements to the subject. Most of the Dublin Core classification schemes don't go much beyond "broader term" or "narrower term". I don't know how the associations would be added to the subjects in the above schemes. ---Suellen Date sent: Mon, 05 Nov 2001 16:22:55 +0100 From: Bernard Vatant <bernard.vatant@mondeca.com> Subject: [tm-pubsubj] Next TC meeting agenda and documents To: tm-pubsubj@lists.oasis-open.org Priority: normal <mailto:tm-pubsubj-request@lists.oasis- open.org?body=subscribe> <mailto:tm-pubsubj-request@lists.oasis- open.org?body=unsubscribe> <mailto:tm-pubsubj-request@lists.oasis-open.org?body=help> [ Double-click this line for list subscription options ] The next PubSubj TC meeting (conference call) will take place on November 20 from 16.00 to 18.00 UTC Phone number to be delivered Three points on the agenda: 1. Draft TC Requirements Document A draft document has been prepared and is visible on-line: http://www.oasis-open.org/committees/tm- pubsubj/docs/requirements.htm Please take time to review it, as well as Mary's contribution to discussion: http://www.oasis-open.org/committees/tm-pubsubj/docs/registry- usecase.htm (It would be fine to start exchanging on those documents on-line before the co-call ...) 2. Editor(s) The chair would like to delegate the TC editor's role to, or at least share editing responsibility with, some english native-speaker(s). Volunteer(s) much welcome. 3. Liaisons Determination of organizations and working groups the TC should work in liaison with, and designation of TC members assuming those liaisons.
