<p>Metacat uses XML for data exchange between the client application and
|
|
30
|
the server.</p>
|
|
31
|
|
|
32
|
<p>XSLT is used for transformations for visual presentation (e.g. XML->HTML).
|
|
33
|
It can also be used to tranlate between different types of heterogeneous XML documents
|
|
34
|
which are symantically similar.</p>

|
<p>Metacat can be set on the fly to either transform or not transform a resultset
|
|
39
|
from XML. This is achieved by setting the 'qformat' servlet parameter to 'html'
|
|
40
|
or 'xml'. When qformat is set to html, Metacat will transform the resultset based
|
|
41
|
on the stylesheet specified in the resultStyleURL of the
|
|
42
|
<a href="./properties.html">Metacat Properties</a> file. This XSL stylesheet
|
|
43
|
defines the rules for how to translate the XML tags into HTML tags.
|
|
44
|
</p>
|
|
45
|
<p>A user can specify that a certain doctype is always transformed using a
|
|
46
|
specific stylesheet by registering that stylesheet in the Metacat Catalog.
|
|
47
|
The Catalog is stored in the database table xml_catalog and contains a
|
|
48
|
list of doctypes and the stylesheets used to transform them. If a doctype
|
|
49
|
has an assigned stylesheet, whenever a document of that type is "read" from
|
|
50
|
Metacat and qformat is set to HTML, the document will be transformed using
|
|
51
|
the assigned stylesheet.
