Subject: Re: Just what is a Core Component? Well, it depends on what "is" is.
Mark Crawford continues to demand "a firm definition of a core component." As Mark is chair of the Joint EWG/X12 Core Component Team, it would be nice if had a definition of the things he's lording over. The definition of a "core" component depends on what a "component" is. Once you had that, you could just add on verbiage that the "core" ones are "really important and central." Now I might be tempted to proffer an opinion that a component is like a class in object-oriented programming parlance, and then work from there. But I would be met reprovingly with "objects carry viruses." So we'll avoid that tack, as I abhor confrontation. A definition of core component should probably not talk too much about XML or other implementation frameworks, so it should remain satisfactorily abstract. Mike Rawlins would insist that we add "syntax neutral" to any description. I figured there must be something in all the old stale Open-EDI and TMWG stuff that could be cut-and-pasted for a definition. ISO/IEC 14662 - Open-EDI, at http://www.ebxml.org/project_teams/jdt/resources/, includes a definition of a "Semantic Component" (SC): "a unit of information unambiguously defined in the context of the business goal of the business transaction. A SC may be atomic or composed of other SCs. SCs are defined by knowledgeable parties such as user groups and proposed for standardisation and registration in one or more repositories...." Is that a start? To Brian Hayes: I have given out the URL for accessing ISO 8601 on a number of occasions on various ebXML mailing lists; e.g., see http://lists.ebxml.org/archives/ebxml-core/200012/msg00019.html, which refers to http://www.iso.ch/markete/8601.pdf. As you undoubtedly retrieved the document from there in the first place, it would have been sufficient to merely pass on the URL. I'm gently hinting that there are ways of avoiding attaching large files to e-mails. Which reminds me: notice that hotels now include a $.10 a minute surcharge for using a local line over 60 minutes? I never paid too much attention to that, as who can talk that much? Well, it came to roost on a slow 34kbs line while downloading e-mail while attending the Washington EWG (and why do the Washington suburbs, in the center of the world, have the worst Internet connections?), as Marcia McClure of the BP group felt it was important to send the same set of multi-megabyte files to multiple mailing lists.
