Lecture 7/tutorial 6

Lecture
This week
SGML- Standardised General Markup Language (the daddy)
HTML - Hypertext Markup Language
DHTML - Dynamic HTML
XML - Extensible ML
XHTML - Extensible HTML
SMIL - Synchronised Multimedia Integration Language.

Historically "markup" is what you would do to a text document to tell, for example to a typist how you want the text to be displayed. Like label whats a heading, or when a new paragraph starts.

With that in mind "markup" is a relatively straight forward term to get to grips with.
Simply adding labels to pieces of text at it's most simple level.

All we need is a set of labels or tags and the method/rules on how they are used.

The Markup language can either be Procedural where the content is "marked up" and the instructions on how the content is going to be displayed are contained within the document or it can be Descriptive where only the content has the markup and the browser decides how the content is to be displayed. (but it will obey certain rules)

The Document Type definition at the start of a web page's code is saying to the browser which particular markup language is going to be used plus where the method/rules are kept. At W3C usually.

What I hadn't appreciated before was that so much of the text of out daily lives is getting the mark up treatment.
Tony's example of google books which I had never seen before has made me realise that I might never need to buy another book, but I may have to buy another screen!

HTML by Tim Berners-Lee is a subset of SGML.


Tutorial
This week I first finished off the FormMail example and checked that I received it's email and validated.
All worked with no problems.
Assignment
I uploaded my assignment Charity website and checked all the links and validation.
Then I edited the FormMail.php file so that the code could be used for my assignment.
New file called FormmailCharity.php.
Uploaded it to my ittwassignment folder on my public site.
This worked first time although I have noticed some typos that will need amending for next week. Ran out of time this week to make it perfect.
Can see no reason why I can't add my header from my charity site to the response page. So this will be something for me to do next week.
Plus must add some comments.

Home Page
I also updated my home page with the link to my assignment. And other than adding the header we made in Media Technologies a few weeks ago I have resisted the temptation to improve the look of my home page.
Since we are doing CSS next term, I think it's best that the content of my home page be simply listed, and that it validates.
I still have to go back and do Tutorial 5. But feel that I'm in a good position in that my assignment is sitting in the folder 95% completed.
