La Casa nel ~Mare~Running away from slavery

In this blog post I’ll make references to my last weekly status report blog post.

I discovered that what I called ‘fromFile’ or fromSource’ properties are already always included in every sensor data instance within the ‘Resource’ field LOL.
However there are some cases in which such properties should be included intentionally because of their utility, for example as a sensor retrieves information about a developer’s focus changing from one source to another one. Then I’ll still check if those properties are available.

Today I made my Restlet server providing more complex RDF data when someone looks up for resource of type ‘File’. This took me a little bit of time but I should be faster with all the other resource types as the mechanism is similar, and I’m going to explain some clue part of it here.
As I have a statement to be added to the model, I check if a statement with the same subject and predicate has already be added, and in case of a positive answer, I add the new one (substituting then, the previous one) only if the time at which that old one statement has been collected (that is the timestamp of its related sensor data) is equal or less recent than the collection time of the new one.

Now every URI is dereferenceable but the information provided by the server for each URI is very poor with the except of the resource types project, user, sensor data type, sensor data, file. I have to enrich info provided for all the other resource types.

Example of info provided as asking for the resource URI:
http://localhost:9875/linkedservicedata/source/file/__home__myrtill__Hackystat_linkedData__mysqlProva__workspace__hackystat-linked-service-data__src__org__hackystat__linkedservicedata__resource__sensordata__SensorDataResource.java

(every ’slash’ within the ‘fullPath’ field is substituted with a sequence of two consecutive underscores)
(consider that I manually sent very few sensor data information and a little set of all the properties that could be set have been set, so this server answer has only a little set of all the information potentially providable).

(I’ve deleted all the ‘<' and '>‘ because of Wordpress conflicts)
