filtering to values more or less than a given property's value

[Augusto Herrmann]

Greetings!

I understand that with a Linked Data API you can filter search results for values of a given property that are greater than (or less than) a certain amount, as long as that makes sense (i.e. for datatypes like int, decimal, float, etc). We can see examples of that on education.data.gov.uk: http://education.data.gov.uk/doc/school

I looked at the example configuration files for that one [1], and searched the Specification as well [2], but couldn't find out how to enable those "more than" or "less than" buttons for the properties establishmentNumber and uniqueReferenceNumber. Apparently that's not defined by use of the api:filter property or anywhere else we could find.

We're using Elda, and would like to see those buttons displayed for the valorDotacaoInicial on this endpoint [3]. Our configuration file is on [4]. The literals have a xsd:decimal type of value.

Any tips?

Hello Augusto,

Are the numeric looking literals in your data data typed?

Oh yes.... If you look in the xsl that generates the HTML you may find that one of the xsd:decimal may be missing from the list of data types used to trigger the <> buttons.

Sorry not in a good place to look properly myself ATM.
