This specification based on the 2000 surveillance studies is published as a technical report (type II) by the surveillance study committee for the next generation network standards, established at the Information Technology Research and Standardization Center (INSTAC) within the Japanese Standards Association. The committee collects technical know-hows considered of significant importance for the promotion of industrial standardization.
This specification defines two languages used to exchange the reference information of shared picture data by using XML.
NOTE: Picture data sometimes represents symbols shared among the users. Requests for functionality to search for symbols (here determining the identity of the symbol in the document in stead of obtaining its attribute content) are often heard. However, since symbols that represent the same concept do not necessarily refer to the same file name or URI reference, in effect such searches cannot be performed without some processing. There might be cases that a set of files for different resolutions or formattings for each conceptually same symbol is provided depending on the capability of the display device in use. Consequently, there is a request that there should be a identifying method independent of the file names or URI references.
Each of picture data conforming to this specification has a unique name in order to distinguish it from others. By sharing those unique names among them, the users may identify them in different documents.
NOTE: This specification only defines the usage of picture names, not picture names themselves.
Specify picture names in XML documents for information exchange that contain picture information. This specification defines a language that specifies picture names described in XML documents.
NOTE: The language must be used together with other XML vocabularies. As a result, you cannot write a complete XML document with this language alone.
This specification also defines another language that describes correspondences between a picture name and its data body (or bodies).
The following standards are part of this technical report as they are referred to in it. They refer to the latest versions. If an RFC is superseded by another RFC, the new RFC is applicable.
