RE: The authority-distribution problem
Negotiated meaning: buy-in from some group informal or formal for documented menanting and rights to change or approve changes to that agreement. Notice the agreement and meaning are two different documents. Costs vary by requirements. If it is a standard, there may be agency/consortia/organization policies for how these decisions are made. If buy-in is not complete you get the OOXML debacle (I won't say which side is the most debac-ed) but the problem is the same. Topic maps provide a means to document agreements as well as a system for implementing them in a readable navigable form. This works well for human readers. RDF and the semantic web provide a means for machines to check agreements and make inferences. A problem with solutions that attempt to document the meaning for multiple communities is they may have different syntactical requirements for documenting that. Another problem is the agreement has to account for the meaning drifting over time (so management rights to make changes to the Record of Authority). IOW, take a simple example such as XML. Is it not changing because requirements are not changing or because the overall cost impact to the entire user community is too great to allow a smaller groups needs to be met (needs of the many vs the few or the one). There are solutions. The problems are will and cause. This is a never ending problem with a managed solution and a maintenance cost. To make that more manageable and to keep the costs in line with small communities, it can be best to manage separate agreements (and schemas) even if they have meanings with multiple communities (overlaps). Otherwise the cost of consensus includes the time to agree and that can be greater than the benefits of sharing. So in the end you must look at the sharing itself and ask how many and what kinds of transactions (messages) are actually shared (not potentially but actually). Until you understand the traffic, you don't know where to put the traffic lights and the signs. len -----Original Message----- From: Costello, Roger L.

Subject: The authority-distribution problem Hi Folks, Last week Steve Newcomb sent a message to this list  that has me very intrigued. In his message he is hinting at problems, and hinting there is a better way. Consider these snippets of his message: The problem keeps coming up: how to distribute, and limit the distribution, of authority over a large-community-wide document type, among smaller sub-communities. Top-down authority over document types simply can't work across diverse human communities. The authority-distribution problem. Distribution of semantic authority. The W3C's focus on machine-to-machine communication and AI left little room for questions about human issues. Different communities communicate differently within themselves, and their syntaxes need to evolve in different contexts with ever-diverging requirements. XML namespace fiasco This story is very far from being over Questions 1. What is "the authority-distribution problem"? 2. What does it mean to "distribute semantic authority"? 3. What story is far from over? /Roger  http://lists.xml.org/archives/xml-dev/200807/msg00024.html _______________________________________________________________________ XML-DEV is a publicly archived, unmoderated list hosted by OASIS to support XML implementation and development.
