For bookmarking sake (and to help me track the concerns), this is an attempt to break out the distinct aspects of the Base URI discussion == GRDDL Source Documents == Where by GRDDL source documents, I mean the documents which correspond to source against which the normative XPath statements are applied. There is an issue of XPath not supporting XML Base mechanisms. We can introduce a notion of a Base URI which is 'top-level' only but follows XML Base in how it is determined (at least with the starting point being the assumption that there is no notion of a base 'inside' == GRDDL Transform Source Documents == XSLT 1.0 is our 'first-class' GRDDL transform and (by virtue of depending only on XPath) also has limitations on XML Base resolution. However, it introduces a 'top-level' notion of the base URI of the document entity which can be passed in to the API and is often assumed to be the URI used to retrieve the source document. == Resolution of Empty URI References in GRDDL Result RDF/XML == If the GRDDL transforms do not output the RDF concrete syntax with the Base URI information embedded, then GRDDL itself needs to provide a consistent Base URI (as the external context). It would seem to follow that the (default) Base URI in this case should the same as the Base URI of the GRDDL Source Document (as determined by XML Base) Though issue-base-param was 'spawned' by conversations on the second category, the tests which was committed (and the corresponding resolution) had more to do with the third category. -- Chimezie Ogbuji Lead Systems Analyst Thoracic and Cardiovascular Surgery Cleveland Clinic Foundation 9500 Euclid Avenue/ W26 Cleveland, Ohio 44195 Office: (216)444-8593 ogbujic@ccf.org Cleveland Clinic is ranked one of the top 3 hospitals in America by U.S.News & World Report.
