Subject: RE: [odata] [OASIS Issue Tracker] (ODATA-1171) Consider using matrix parameters for filter segments
The use of ";" was defined as a param rule in clause 3.3 Path Component of rfc2396. That rule is deprecated in rfc3986 and replaced with a more relaxed syntax. So... still available and should be supported. The one issue with both formats is that a query portion ("?") is not required. The query portion is a trigger that suggests/requires the response not be cached. Can we say that any URI that uses characters from the sub-delims rule should also not be cached?

It turns out, the facility to append parameter information to a segment was defined many years ago using "matrix parameters" -- basically, a matrix parameter is a way to add a parameter to a path segment using a semi-colon (and, in many cases, can be used instead of a query string parameter, which is exactly the scenario we are trying to enable). 4.01 CS01 syntax: Customers/$filter=@q?$@q=name eq 'Smith' Matrix parameter syntax: Customers;$filter=@q?$@q=name eq 'Smith' Advantages of using matrix parameters: 1) Not inventing something new 2) May already be supported by some systems 3) Similar to syntax for nested expand (and now select) options -- This message was sent by Atlassian JIRA (v6.2.2#6258) --------------------------------------------------------------------- To unsubscribe from this mail list, you must leave the OASIS TC that generates this mail.
