XTM::LTM 0.37

XTM::LTM is a Topic Map Parsing of LTM instances. SYNOPSIS # reading a topic map description from a file/url $ltm = new XTM::LTM (file => mymap.ltm); $tm = $ltm->sync_in(); This package provides parsing functionality for LTM instances as described in the package documentation (doc directory) or at http://www.ontopia.net/download/ltm.html Following clarifications and deviations relative to the LTM specification hold: comments: The parser does NOT recognizes nested comments. Any closest following */ sequence terminates a comment. scope: Only exactly ONE topic can be specified for a scope, but violations are currently not captured (open issue). role type: If a role is not specified, it will remain empty and not - as the specification mandates - will be substituted by the topic type. The reasons for this are that, first, a topic might have several types (which one to use?), secondly that there might be several topics in a member and thirdly, a role should generally NOT be the type of a member. This approach would somehow violate the idea of roles in associations, so this should not be encouraged by any tool. merging: Merging happens according to the XTM standard. This may affect the item 4 of section 3.2 according to which topics may be merged without error having different subject addresses. encoding: Only the encodings supported by the local Text::Iconv module are supported. BASEURI directive: Not (yet) implemented. TOPICMAP directive: Not implemented. This directive can give a name to the current topic map. The idea is that this name can be used inside the map to point to the map. An example would be a topic reifying the map. As the map is a resource (either explicit or via a map expression, XTM::Virtual), there seems to be no good reason to provide an additional name. MERGEMAP directive: The HyTime, ISO13250 format is not implemented as there is currently no driver in XTM::base. The strings determining the format are checked case-insensitive, so ASTMA and AsTMa are treated equally. The location of the map can be defined via any URI handled by LWP::Simple. If no scheme is provided file: will be assumed. The format string can be omitted. Then the parser will interpret the location string as tau expression (XTM::Virtual)..
