There are some data types that can have a precise syntax and that can be checked when typed in an input text box. This data, written with their precise syntax, can be used also to semplify tasks in the everyday life of the average internet user.
For example, we could instruct our browser to open data identified as a place address with our preferred online mapping service (i.e. Google maps), exactly as we open our preferred e-mail client when we click an e-mail link.
We could also save place addresses exactly as we save an url or a vcard.
If an input text field is identified with a type=”email” attribute, the browsers could also automatically check the correct syntax of the user typed data and suggest corrections, exactly as some websites already do.
Every resource (a book, an e-book, a web site, but also a movie, a music etc.) can be divided in sections.
Sections can be:
A subsection is a section contained in a section. A subsection can contain another (sub)section, so there are sections of different levels (first, second etc.)
I think it’s fundamental to distinguish different types of content organization and, consequently, fruition:
In an hypertextual resource we can always suggest a preferred linear path, that explores sequentially the whole content.
Writely is going to become a new application of Google services. At midnight of 20 September 2006 I have received an email from the official Writely team (noreply@writely.com) signed as “ Google Writely Team”. The text of the email is:
In a few days, we will update your Writely account to use your lorenzo.detomasi@gmail.com Google Account registration settings.
This means you’ll need to use your Google Account password when signing in, not your Writely password (if they’re different).
If you’ve forgotten your Google Account password, just go to https://www.google.com/accounts/ForgotPasswd
Thanks!

The role attribute takes as its value one or more white-space separated QNames. The attribute describes the role(s) the current element plays in the context of the document. It is used by applications and assistive technologies to determine the purpose of UI widgets. In the case of a web page it may be declarative as a function of particular elements or it may be an attribute which is configurable by the page author. Additionally, role information may be used to define each action which may be performed on an element. This allows a user to make informed decisions on which actions may be taken on an element and activate the selected action in a device independent way.
- main
- This defines the main content of a document.
- secondary
- This is any unique section of the document. In the case of a portal, this may include but not be limited to: show times; current weather; or stocks to watch.
- navigation
- This is the navigation bar on a web document. This is typically a list of links to other pages on the site or other areas of the same document.
- banner
- A banner is usually defined as the advertisement at the top of a web page. The banner content typically contains the site or company logo and other key advertisements for the site.
- contentinfo
- This is information about the content on the page. For example, footnotes, copyrights, links to privacy statements, etc. would belong here.
- note
- The content is parenthetic or ancillary to the main content of the resource.

Authors may use the following recognized link types, listed here with their conventional interpretations. A LinkTypes value refers to a space-separated list of link types. White space characters are not permitted within link types.
These link types are case-insensitive, i.e., “Alternate” has the same meaning as “alternate”.
User agents, search engines, etc. may interpret these link types in a variety of ways. For example, user agents may provide access to linked documents through a navigation bar.
- Alternate
- Designates substitute versions for the document in which the link occurs. When used together with the
hreflangattribute, it implies a translated version of the document. When used together with themediaattribute, it implies a version designed for a different medium (or media).- Stylesheet
- Refers to an external style sheet. See the Style Module for details. This is used together with the link type “Alternate” for user-selectable alternate style sheets.
- Start
- Refers to the first document in a collection of documents. This link type tells search engines which document is considered by the author to be the starting point of the collection.
- Next
- Refers to the next document in a linear sequence of documents. User agents may choose to pre-load the “next” document, to reduce the perceived load time.
- Prev
- Refers to the previous document in an ordered series of documents. Some user agents also support the synonym “Previous”.
