Definition
- It defines the structure of all information of Virtual Entities only at conceptual level and not at concrete level. In other words, it covers all aspects of adding information in the data. Here, structure covers attributes, relations and services that helps to know what, who, where, and when.
- The detailed representation of information is not covered in this model.
This model covers following details (elements & their association) and of modelling of virtual entities:
1. Virtual Entity has attributes with name and its type.
- Each virtual entity has a unique id or type i.e human, a car, or a temperature sensor.
- A virtual entity can have zero to many attributes.
2. Attribute can have one or more values.
- Each attribute has a name, a type (semantics) and one to many values.
3. Value has meta information(Meta data)
- Value can further also have more values and each value has zero or many meta data. A virtual container keeps grouping of a value and associated zero or many meta data.
4. Meta Data might help to define other information like:
- Time stamp (what time information is defined)
- Location (Location where measurement took place
- Quality (Quality of measurement) etc.
Meta data can itself have additional meta data i.e unit
