change in the diagram. Alignment  with the latest conceptualization of voltage

update on the comment of ic-data:GaussianDatapoint

removal of max qualified cardinality with blank node at the bottom

removal of description of the domain of ic-tplg:hastopologicalassociation from ic-data

typo correction

change of datatypeproperties in object properties (in time ontology, interval is a class)
removal of suproperties relationships because of conflicting range domain with the superproperties

device_3 example individual removal

removal of a duplicate property (we have that conceptualization in hasoperationmode)

ic-flex ttl file in line with the latest conceptualization

-	I have internally (in the ttl file) re-defined om:hasprefix because it was giving an error.

-	I added the objectproperties includescommand and concernsdevice. They were not present in the ttl model.
-	I removed the restriction on user profile at the level of the preference. We already use the domain and range on preference.
-	I added the object property belongstouser (which was present in the diagram but not in the model).
-	I added the objectproperty hasLocation
- I put a restriction on the class preference.

-	In the diagram, I have added the class measurement phase difference and the instances of this class (which were defined in the model).

-	In the ttl file, schema:place and acmeasurementphase were defined as subclasses of topological location. However, in the diagram and examples they are not subclasses of topology. So I moved their position to classes in the ttl.file
-	I have inserted distance as the subclass of topological location (we use distance in the example and is conceptualized in the diagram)
-	I have added a basic comment to acmeasurementphase
-	I added a comment on voltage
-	I defined the object property haspoint. I put a domain range restriction on this property.
-	I defined the property isInsubgridOf with a domain on Device
-	I changed the name of the property hasMeasurementphase to hasACphase (as defined in the diagram).  I removed the domain (device) from this property since it is used also for GridSegment
-	I defined the property isinACphase
-	I defined the property ISACPhaseof
-	I defined the property hasACphase
-	I defined the class ACPhaseName
-	I instantited the individuals of ACPhaseName
-	I defined the objectproperty is topological association of
-	I defined the object property hasphasename

-	I changed the diagram from ic-fc:hasquantile to ic-data:hasquantile (since in the ttl models are both defined as ic-data:hasquantile)
-	I changed the gaussiandatapoint from ic-fc to ic-data in the diagram (according to the definition provided in our ttl model)
-	I changed the property has stardarddeviation from ic-fc to ic-data in the diagram
-	I changed the color of the arrows hascreationtime/etc. from the diagram because the previous ones where white at the top (they were indicating a subclass relationship according to our use).

I have added a restriction on forecast via has topological association as defined in the diagram

I added the class DeviceCluster that we use in the example and I defined it as a subclass of saref:device.

-	I added the objectproperty belongsToTimeSeries to the diagram.
-	I modified the diagram and added ic-data:hasquantile (which was defined in the ttl file)

-	I added the object property ic-data:containsquantity (defined in the diagram and used in the examples).
-	I added the comment to the class ic-data:usage (I took it from the deliverable).
-	I added the labels to the individuals of Ic-data.
-	I added a comment and label to ic-data:Message
-	I added the restriction at the level of datapoint via property hasTopologicalassociation)
-	I added a label and basic comment to the objectproperty  belongsToTimeSeries.
-	I added a label and basic comment to the objectproperty  hasdatapoint.
-	I added the label and comment to ic-data:hasUsage.
-	I added a label and comment to the datatypeproperty ic-data:hasTextValue.

- remove power limit profile, since it's the same as PowerEnvelope
- change prefixes to ic-s2
- make ic-s2 profiles subtypes of the generic ic-flex profiles
