WHAT IS MEDIA

MEDIA VS. MEDIA Single Source widely variant ‘media’ at acceptable levels of quality?

Traditional associating stylesheets with instances 1. Hard Coded – all xml through same stylesheet, perhaps change by media location. Complicates introduction of new XML 2. Declarative – Use this XML with this XSLT. Requires knowing what XML and What XSLT matches it. 3. Location based – any XML from this location passes through a particular stylesheet. Requires limiting the document types in locations. Bad for Application Building. 4. Based on Validation, Doctype – mod_xsl Erlang. Tight Coupling of Presentation to validity. Requires support of multiple validation engines to achieve multiple input formats. Unworkable.

New Associating Stylesheets with Instances If stylesheet = test_{mediachannel}.xsl If stylesheet = http_www_example_org_test_{mediachannel}.xsl If stylesheet = mytest_test_{mediachannel}.xsl If stylesheet not found, go to next closest match, if no match: Stylesheet = {mediachannel}_generic.xsl stylesheet= mytest_test_{mediachannel}.xsl
