To use create a data html page consisting of one table with the first row being "keywords" which will correspond to special tagnames in a template html. Two required keywords being "wiclass" which is a unique name for each row/instance. And "wiprotourl" which is the relative or absolute path to the specific prototype(template) page for that instance. These can be anywhere in the table, but for convenience they ought to be the first two columns. After building this data table, create a proto page (or pages) which contains a single set of html which will be inserted into your page (like a library item). Insert in the proper locations tags which have the names corresponding to the column heads in your data table. For instance if you had a column called foober, you would insert <foober></foober> somewhere in your prototype html page. Finally, to insert this instance into a regular web page somewhere, find the location on the regular page, and insert a
<webinstance class="something"></webinstance> into the page, where "something" corresponds to the wiclass value you want. See example pages and tutorial for help.
