<p>Metacat is implemented as a Java Servlet, and so communicates using basic
|
| 59 |
|
|
HTTP protocol semantics. The figure below shows the basic structure of
|
| 60 |
|
|
the Metacat architecture. A well defined interface for inserting,
|
| 61 |
|
|
updating, deleting, querying, and transforming (using XSL) XML documents
|
| 62 |
|
|
is presented. We would like to add the DOM API as an alternative
|
| 63 |
|
|
supported mechanism for interacting with Metacat, but have not yet
|
| 64 |
|
|
implemented this functionality. </p>
