XML Born
XML (Extensible Markup Language) 1.0 standard was published February 10, 1998.
XML was born from the
shortcomings of SGML [Structured Generalized Markup Language] which was hugely complex, massively flexible and just plain hard to work with for many developers.
XML has taken off
because it has all the best of SGML without many of the weakness.
XML Goal
XML took us beyond mere presentation of information and into the realm of representation of information. This content is not just a mass of data to be rendered solely for viewing on a web browser. Now the content could be structured and the meaning attached to this
structure could be transmitted as well.
HTML's difficulties:
1- HTML does not reveal anything
about the information to which HTML tags are applied.
HTML
tag names don't describe what content is, they only imply how content appears.
For example the html tag "Microsoft"
appears on a web browser but HTML can not tell is it a computer corporation? A Software? A Brand name?
2- Web
applications relied too much on scripts at the server to process the data.
This makes the web slow and contributes to internet traffic.
3- You can't add new tags to HTML Language that are meaningful and useful.
4- HTML is a presentation
technology only.
XML Success
The Java technology, enables browsers to function as generalized application platforms. The result is True platform independence. XML provides information rich in metadata specified in a standard format, XML and Java technology make it possible for more of an application's
work to be processed at a client side. This contrasts with the tendency of HTML pages to rely on a script back at the server. With XML and Java technology, more client-based application processing could reduce network and internet traffic, making the web faster.
XML challenges
Converting any information from a
display format such as HTML, RTF, MIF, or PostScript to a
structured format like XML will require that you understand what
your information really
contains. This requires a document
analysis and the determination of information semantics on
which different parts of your enterprise rely. Many enterprises
in different business sectors
have established industry
standard information models that can be expressed in XML and,
more
importantly, can be shared.
Once the relevant information models and their expressions in
XML are constructed, the effort
to convert existing
information into the XML format can proceed. It may or may not
be painful,
depending on the condition of the existing
documents. These efforts can be done in house, or they
can
be completed with the help of qualified consultants.
XML Resources:
Easy XML is a simple XML editor that aids in the rapid building of XML applications.
Microsoft XML for SQL Web allows you to query database tables and receive the results as an XML document.
Microsoft XML Notepad is a simple HTML prototyping application for building and editing small sets of XML-based data.
Microsoft XML Validation Tool checks that an XML file is well formed.
XML Spy is a powerful XML editor.
XMetaL
is an advanced, simple-to-deploy XML authoring tool that delivers an unprecedented ease of use.
