CST(74)-Compound Documents And The Object Web

A compound document is a framework for organizing collections of components- both visually and through containment relationships. A document essentially a collection of site for components and data that can come from various sources.

Compound documents provides two key technologies:
  1.  Visual component foundation for open web browsers.
  2.  Container technology or distributing, caching and storing groups of related components and their data. (Shippable places).
Compound Document as open Web Browsers

Web browser built entirely from components. Imagine that the Web browser itself is a visual container of components. This means that you should be able to embed components within other components and then move them around at will across documents, desktops, and networks.

You can resize it, zoom it, and visually rearrange the contents of the page in any way you want. For example: You will be able to drag a URL and drop it on a button to create an active pushbutton.

Compound Document as Portable stores

One of the key piece of a compound document technology are the portable structured files they provide to store and distribute components. The two best-known examples of such containers are Open Doc’s Bento file system and OLE’s compound files (also known as DocFiles) They both let components store their data in self describing, navigatable data streams.

Structured containers allow us to store multiple components in a single document, move them as a single unit across the network, cache them where it makes most sense and store them in document databases. The component store also becomes a unit of defense for an entire set of components.

Components need component stores so that you can move them around the Web at will. Structured containers are lightweight, shippable, object databases that were designed specifically to store, manage, and transport components.

Shippable Place:

A place is a visual ensemble of related components. A shippable place is a mobile container of components; it’s a place that can be shipped over the Net. Shippable places let you interact with multiple places that represent collaborative environments based on real-world models. A place is a mini virtual world. A place is implemented as a collection of components stored in a structured file container. A place is typically used to display components that represent people and things.

For example, places can represent meeting rooms, libraries, offices, homes, stadiums, shopping malls, and museums. People live, work, shop, and visit these places. Things are tools that help us communicate, interact, and work within these places.

Once the place is secured on your desktop, it will serve as a visual front-end for all kinds of specialized Internet services and business objects.
