Choose ontologies and predicates for additional class and instance description fields

For now, we use SSN as base ontology to describe device model(ssn:System), sensor(ssn:Sensor), and their relation(ssn:hasSubsystem). The minimum viable JSON-LD graph now is looks like:

  "@graph": [
    {
      "@id": "http://semdesc.semiot.ru/heatmtr100",
      "@type": "ssn:System",
      "rdfs:label": "Heat Meter #6500",
      "ssn:hasSubsystem": [
        {
          "@id": "http://semdesc.semiot.ru/heatmtr100/sensor/0"
        }
      ]
    },
    {
      "@id": "http://semdesc.semiot.ru/heatmtr100/sensor/0",
      "@type": "ssn:Sensor",
      "ssn:observes": {
        "@id": "hmtr:Temperature"
      }
    }
  ]

There are some valuable parameters, that should be contained in description: manufacturer and version for model description, unitsOfMeasurement, accuracy and sensingPeriod for sensors (maybe something else?). I suggest to describe in this issue ontologies(prefixes) and possible examples for this fields.
