Not parse empty sampling rate #6

Closed pasqLisena closed 6 years ago

pasqLisena commented 6 years ago

If there is no sampling rate, do not add the property. http://data.doremus.org/rate/

rtroncy commented 6 years ago

http://data.doremus.org/rate/ is an instance of ecrm:E54_Dimension? When is this instance created?

pasqLisena commented 6 years ago

We use Dimension for specifying the sampling rate. It is created with the Recording. http://data.doremus.org/recording/2ec53e9c-eab8-3451-8312-cd6980a66ec4.

This is instead a correct example (48kHz): http://data.doremus.org/rate/48

rtroncy commented 6 years ago

This is what I saw. Do we really need this long path F26 -> P43 -> doremus/rate/xx ->P2 -> dbpedia:Sampling_rate ? Don't we want to re-use an existing property rather than creating instances of P43?

http://lov.okfn.org/dataset/lov/terms?q=sampling+rate provides some possibilities

pasqLisena commented 6 years ago

So, looking around, the best candidates are:

http://dbpedia.org/ontology/frequency
https://www.w3.org/ns/ma-ont#samplingRate (ttl) (+1 from my side)

(all in Hz, multiply by 1000 the kHz)

rtroncy commented 6 years ago

I would favor http://dbpedia.org/ontology/frequency ... which is more used.

ma-ont:samplingRate is defined as "an audio sampling rate where the units are defined to be samples/second."
