HTML, XML, and all that |
- HTML - HyperText Markup Language - SGML derived
- Intent is semantic markup of text
- Has been kludged to death; now includes typographic information
- Cannot be extended easily, cannot be parsed without DTD, and even then, building a parser is very hard due to all the existing broken HTML
- XML - EXtensible Markup Language
- Always parseable, can be reliably parsed without DTD
- Not just for text - think: semantic markup of information
- Various stuff being built on top - e.g. RDF, etc.
