updated CmpE 583 Fall 2008 Discussion: XML Proc.- 3 Concern: Semantic Web & XML Advantages & Disadvantages of XML Everyone lauds XML; it’s the foundation of semantic web and mother of all to happen. Advantages are awesome. Disadvantages:  Hardly any one discusses this subject. Throw “disadvantages of XML” at Google. Then, try “advantages of XML” and see!  See Weaknesses of XML in a DevGuru tutorial (circa ~2000?) or WDVL Tutorial (circa 1999): reasons are no longer valid, except for “verbosity” complaint.DevGuru tutorial WDVL Tutorial Summary critic of XML. Summary critic If not XML, what else could we use? Keep in mind the principle of separation of data and rendering apart. SGML?!!!!!! Graphics??? XML also being infused more and more into other technologies.  See: Next slide.

updated CmpE 583 Fall 2008 Discussion: XML Proc.- 4 Concern: Semantic Web & XML Native XML support in ECMAScript? ECMAScript: aka Javascript. Provides client side XML processing. In your opinion:  Is it worth the effort?  Future senario? Why not: semantic client?  Other issues?  See: Initiative for new the ECMAScript Standard E4X.ECMAScript Standard E4X  See: ECMA for other standards, such as C#,.NET F/WECMA Ajax support for XML?  Ajax supplies clean XML support allowing full XML documents to be streamed to the client for rich messages which are easy to process via standard JavaScript DOM support [Ref: ActiveMQ].ActiveMQ  As we said in our Enterprise AJAX overview, AJAX is a recent term (early 2005) for leveraging the communication, XML, and CSS capabilities of modern browsers via JavaScript.
