We wish to express our deep appreciation for his contribution to the work of the committee and wish him well in his new job. ТТDoug Mann received from Paul Hawes the material documenting the current version of the metamodel. Doug is translating the material into a form editable with the software packages that Doug has available. He has recreated the graphic for the metamodel, using PowerPoint. In so doing, he raised a number of issues to be resolved. He is also translating the text and graphics of the public review document. Doug invites comments from the X3L8 members as input to his effort to prepare this material for the second public review. Doug passed out copies of his new material and is putting his versions up on the X3L8 FTP server. ТТHenry Heffernan agreed to develop some introductory material for the Metamodel for the Management of Sharable data. This introductory material will provide some historical context and help people to understand the usefulness of the metamodel. Andy Schoka and Burt Parker will provide Henry some potentially useful material. ТТDoug Mann will prepare MSWord, HTML, and PDF versions of the April 1УУstФФ version of the draft Metamodel for the Management of Sharable Data. He will put these versions and the PowerPoint version of the metamodel graphic on the FTP server.

These include: ТТ o Metamodel extensions for application data elements ааАм` И hРpШ xа (#џџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџА` И hРpШ xа (#џџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџААааТТBill Kenworthey has long talked about "attribute steaming" ЉЉ the addition of attributes as we go through progressive steps from design of a "generic" or "abstract" data element to design of a data element actually used in a particular application. At the abstract level, a data element could be used in many applications and is documented with a set of attributes. For a data element is used in an application, we can specify additional attributes describing, for example, how and for what purpose the application collects values for the data element. We have not have not specified the additional attributes in the current metamodel. Now that we have reference implementations of the metamodel in place, we may be in a better position to address this topic. o Electronic data communication ТТData elements can be combined into messages. The structure of the message may be recorded for any message, including EDI X.12 transaction sets and UN/EDIFACT message sets. This could also include new structures that may be designed for Web communications. We may need additional structures in the metamodel to capture this information or to adequately describe the data elements used in messages. Prototype work is underway to accommodate this type of data. o Managing domains ТТIn some cases there are value and/or conceptual domains that are the focus of maintenance efforts. For example, country, state, and county names/codes. If we focus our attention on this aspect (managing domains), we may want to revise some aspect of the metamodel. For other data, the focus may be much more on management of the "concept" and less focused on the domain. o Capturing different classification systems ТТWe need to explore the use of our classification structures for capturing different types of classification structures. If ERDs can be considered as a type of classification structure, it should be possible to capture this model information about any data element. Alternatively, some taxonomies or ontologies might "classify" the data element quite differently. This could resolve different views of what information is contained in the Object Class, Property and Representation attributes of the current metamodel.  Topics to be explored at the next two meetings: ааА` И hРpШ xа (#џџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџАм` И hРpШ xа (#џџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџААааТТТТС€Сa.ССLook at some data elements or groups of data elements in the Environmental Data Registry.
