semtags
Tag for-each-buffered-result

A convenient loop tag to directly iterate over the results of a SPARQL query. The result is buffered and if the tag is called again with the same query and reset="false", previous results are reused to save time. This can be useful for instance for paginated results. Variables appearing in the SELECT clause are created and updated in the JSP context for each iteration e.g. SELECT ?name ?age { ... } means ${name} and ${age} can be used directly in the body of the tag.
