20-Nov-12). How to use if expressions and functions in an Aspire tag based html (Howto)

Aspire allows "if" tags in your html pages. Here is an example.

<!--RLF_TAG BGN_IF aspire_key_name=literal_value if1 -->
..html segment
<!--RLF_TAG END_IF aspire_key_name=literal_value if1 -->

Aspire will take the "aspire_key_name" and try to locate it in the aspire data set. If it is there its value is taken and compared to the literal_value. The key is not case sensitive but the values are. If the strings are the same (or match) then the html segment will be included in the page otherwise not.

This is an important read to configure aspire for uploading files

9-Nov-07). How to use Generic Mappers (Howto-Advanced)

Generic mappers are a set of java classes used to quickly read key value pairs. For example the relationship between file extension and their content type is determined this way.

This mechanism is intended to be a general purpose mechanism for reading a dictionary of values

The current implementation is a bit inefficient but a future implementation can amend that.
