Hi Krzysztof, What I am trying to get at is a coherent ontology of attributes that can be used for mapping ABox instance data for integration and interoperability purposes. The general idea is to have a reference grounding upon which external semantic datasets can co-reference as a bridging mechanism. As one example, let's say that dataset A describes location of an entity with the attribute country, and only provides literal values, whereas another dataset B describes location with object properties by ISO country code. The reference grounding could be an ontology with the complete listing of ISO country codes. This is not the simplest example, since the literal in dataset A would need to be evaluated and lifted to the reference object property. Probably some user interface would need to be involved to reconcile uncertainties, making the process semi-automatic. Other examples may not involve lifting, but may involve unit conversions or other manipulations. Those, too, would likely need to be semi-automatic. On the face of it, the scope may sound daunting. But, my observation is that most attributes (explicitly used to describe entities) follow a Pareto distribution and the number of commonly used attributes (say, between schema.org, Wikidata, and other leading KBs) is tractable. Once a suitable design and starting framework was in place, grounding values could continue to be expanded, as well as possible lifting and conversion utilities. The advantage of this approach to dataset/KB authors is that only one mapping need to be made to the reference grounding. Thereafter, other datasets mapping to the same attribute(s) could be inspected for possible interoperability. UMBEL, as a subset of Cyc, already has about 2000+ of its concepts already assigned to the attribute SuperType [1]. I was able to rather quickly pull together one initial high-level view for 90 or so of them to construct what such a attribute concept structure may look like: Attributes ObjectValueCharacteristics StringObject StringDatatype_Unlimited List_Information FrequentlyAskedQuestionsList MailingList AlphabeticalList Index_List_Information BullettedFormat UnitOfMeasure UnitOfDistance InternationalUnitOfMeasure UnitOfMeasure_Common NaturalLanguage Encrypted AuthenticationSource PersistenceDistribution Uniform_PersistenceDistribution UnitOfMeasureConcept Ratio CollectionType Phase EmptyCollection Preference Quantity AttachmentAttribute WrittenInfo StructuredInfo VisualInfo AudioInfo LogicalFieldAttribute TruthValue EntityCharacteristics DescriptiveAttributes Definition_PCW VisualPattern SpatialThingTypeByShape ShapeAttributes Color Name Title EnumeratedAttributes EconomicalQuantity DispositionalQuantity MentalQuantity PhysicalQuantity Quality SocialQuantity MeasurableQuantity TotallyOrderedQuantityType QuantityType NonAspectualQuantity EnvironmentalQuantity ActionAttributeLevelQuantity EmotionalQuantityType LocationAttributes OrientationAttributes GeographicalPlace MappableAttributes ContactLocation PopulatedPlace TimeAttributes HistoricTemporalThing Time_Quantity EventAttributes TimeInterval TemporalThing IdentificationAttributes ContactLocation ReferenceWork IDString UniqueID SituationAttributes Situation Qualifier Statement Collection 'Ordered Collection' Individual 'Concept Scheme' Class Concept Statement Class RefConcept This is *very* preliminary, and some of the names don't yet feel right. Also, there are some new concepts added (which need to be checked in Cyc) for better organization. But it does try to capture one more-or-less high-level view of the outlines for this structure. SIO has a different, but similar, approach. I am purposefully excluding "relations" between entity types in this thinking. Rather, I am focusing strictly on the instance descriptions and characterizations (attributes). For the attributes as defined, however, both bundles and hierarchies are of interest. Does this help? If so and there is a relationship with your own geographic interests, perhaps we can talk offline. Since I envision this reference grounding having common use, geographic attributes would definitely be included, as shown above.
