Include timestamp when listing a profile

[acorbi]

In order to keep record when a profile has been listed, a timestamp field can be added on the listing JSON files.

@elf-pavlik @almereyda what do you think? Should we just add a "@Updated" attribute together with "@id" and "@type" ?

An example would be something like this:

{
"@id":"http://profiles.open-steps.org/directory/7ce5f07a-1c3c-4e35-90c9-e51bce25e04a",
"@type":"Listing",
"@Updated" : "13/11/2014 20:04:00",
"@context" : "http://plp.hackers4peace.net/context",
"@graph" : "{
....

I wonder what is the best choice for the date format. Should we just use time in milis? That raises the question whether the profiles have to be also human readable.

I like ISO 8601 for that case.
