Re: Groves? Please ::choke::..
* Guy Murphy | | Now up until the last bit this sounds like DOM. Are groves just an | object model? In a sense, yes. However, the DOM is an API, while groves are just an abstract data model. (It's easy to create an API for it, but the standard doesn't do that.) Groves consist of two things: nodes and their properties. Properties can be named lists of nodes, lists of nodes, single nodes or simple data (text, numbers etc). Also, groves have what are called property sets which you can think of as a set of class definitions (or struct/record definitions) in a programming language. There is a default property set for SGML and that more or less corresponds to the DOM. However, you can also define property sets for, say, MPEG files and RTF files. And since HyTime is based on groves, this means that you can address into those kinds of data as well once you've defined their property sets. So, in a very real sense, groves are all about liberating the data from the syntax in which they are enslav^H^H^H^H^H^Hserialized and expressing their internal structure conceptually. --Lars M. xml-dev: A list for W3C XML Developers.
