None of these foundation properties are unusual; they are all used in reasoning everyday:Individuals, things that exist in 3D space and time, i.e., have spatial-temporal extent.Types, sets of things.Tuples, ordered relations between things, e.g., ordered pairs in 2D analytic geometry, rows in relational database tables, and subject-verb-object triples in Resource Description Framework.Whole-part; e.g., components of a service or system, parts of the data, materiel parts, subdivisions of an activity, and elements of a measure.Temporal whole-part; e.g., the states or phases of a performer, the increments of a capability or projects, the sequence of a process (activity).Super-subtype; e.g., a type of system or service, capability, materiel, organization, or condition.Interface; e.g., an overlap between two things.Three types of Things: Types (which are like sets), Tuples (ordered relationships), and Individuals (not persons, but Things that have spatial and temporal extent – spatio-temporal extent.)mereology is a collection of axiomatic first-order theories dealing with parts and their respective wholes. In contrast to set theory, which takes the set–member relationship as fundamental, the core notion of mereology is the part–whole relationship. Mereology is both an application of predicate logic and a branch of formal ontology.or

Rigorously worked-out common patterns are reused Saved a lot of repetitive work – “ontologic free lunch”Concentration of rigor on common patterns results in higher quality and consistency throughoutModel compactness -- DM2 is tiny compared to its predecessor by two orders of magnitude!Easier to learn -- a few hard concepts are easier to learn than thousands of conceptually intractable ones.Implementations get reuse too – same code, queries, … work for many datasetsSuper/Sub Type, e.g.,F-15 is type of FighterWhole Part, e.g.,AEGIS radar is part-of the AEGIS shipOverlaps, particularly Interface Type, e.g.,Asset data collection activities produce data for audit reportingBefore-After, e.g.,The collection task takes place before the posting and exploitation tasks

Additionally, the GWG provides a standards-focused forum that the NSG community can use as a means to exchange and communicate issues regarding GEOINT standards requirements, development, implementation, and conformance. The GWG recommends GEOINT standards for data, systems, and their interfaces to ensure interoperability with DoD and non-DoD systems. The GWG serves as a community-based forum to advocate for Information Technology (IT) standardization activities related to GEOINT. In this capacity, the GWG supports the Director of the National Geospatial-Intelligence Agency (NGA) in carrying out GEOINT functional manager responsibilities for standards. The GWG performs two major roles: 1) as a technical working group (TWG) of the ITSC, with all the responsibilities of an ITSC member and, 2) as a coordinating body for the GEOINT community to address all aspects of GEOINT standards. Through the GWG, community consensuGlobal Force Management (GFM) GFM is a process that enables insight into global availability of US forces, and provides a means to assess risks associated with proposed allocation, assignment and apportionment. GFM data will be transparent, universal and accessible on demand in a net centric environment.Global Force Management requires the implementation of a common force structure, for which there are three key elements. 1. A joint hierarchical way to organize force structure data for integration across Service-lines, known as the Force Structure Construct (FSC). 2. Force structure data that is rigorously specified via a GFM Information Exchange Data Model and its semantics unambiguously defined so that sophisticated computer programs can economically exploit it via the net-centric data strategy. 3. A common naming convention and data tagging technology, known as Enterprise Wide Identifiers (EWIDs), that must be accepted and used across DoD (including adoption by future Joint systems such as DRRS, DIMHRS, and Blue Force Tracker), with thGPS Based Positioning Navigation Timing Service - GPNTS To provide Positioning, Navigation and Timing (PNT) solutions to afloat combat systems.Integrated Fires Fires Knowledge Network (FKN) is for all Fire Support and Field Artillerymen no matter where their mission may take them.

19 6. Semantic Precision for Heterogeneous Data Integration Human-interpretable onlyA spectrum of information sharingHuman-interpretable but with a predictable organized arrangementMore structure than structured textNamed records (or tables or classes) that are some sort of container for named fields (or attributes or columns). Associations and relationships, containers can point to information in other containersBecause of the labeling, you can tie the information together and query them. A SQL query is just fundamentally a selection of the information. Referential integrity, data validation, cardinality rules, etc.Applicable mathematics:Set or type theoryMereologyMereotopology4 dimensionalismPredicate calculusLogics: modal, Kripke, …Rules, operators:Commutative, reflexive, transitive, …Member-of, subset-of, part-of, …Let's start generally: "unstructured data", e.g., free text, might be considered one end of spectrum and math (numeric or symbolic) another.But even so-called unstructured free text can have structure, e.g., the OMG RFP template. Why do we do semi-structured text? There's a step to understanding what we’re doing. Why do we do databases? There's another step.The shortcoming of databases is that they usually have little more semantic structure than structured text -- named records (or tables or classes if you wish) that are some sort of container for named fields (or attributes or columns). Via associations and relationships, containers can point to information in other containers. Because of the labeling, you can tie the information together and query them. A SQL query is just fundamentally a selection of the information. I don't think there's much going on besides that. As for referential integrity, data validation, cardinality rules, etc., it's handy to go back to the semi-structured analogy and see that they just tell you what parts of the form or template have to be filled in, with what choices, what the rules are for cross-references, etc.Math does a lot more. Let's just talk about logical entailment in this . Given, "I have a headache", how do you entail, "I have pain", unless you have a categorization of headache as a type of pain? You won't get that from unstructured or semi-structured text, or database structure or SQL. It's "common sense" to you but computers have no more common sense than a light switch (or even a few million light switches).Let's make this more relevant to EA. "F-16C has a speed capability of Mach x" ==> some F-16's have a speed capability of Mach x"F-16's can fly at least Mach y" ==> F-16C's can fly at least Mach y"Ship's Self Defense System can parse and generate TADIL-J messages" and "SSDS is-part-of all CVNs" ==> CVN's can parse and generate TADIL-J messagesI could go on and on. Without the "intelligence" to perform entailment, data integrations, queries, and analysis algorithms miss connections. I cannot even remember all the EA data integration and analysis routines I've seen over the years that flopped for this reason -- it is a real problem. I'd bet Ian has lotsa examples too. The C4ISR community has problems with semantic imprecision too.My basic point is that we computer scientists think we're doing a lot with computers when we use databases but it's really just storage and retrieval with connections only for exactly matching pieces of information (e.g., "keys" or exactly matching strings). Reasoning requires a lot more and entailment is an important part. IDEAS supports entailment and other sorts of mathematical understanding of the data with membership (~ set theory) and 4D mereotopology (parts and boundaries). It only seems academic at first because it's so fundamental in human reasoning that it's hard to see that computers don't have it at all and that they need it if we want to use them for something more than just storage and retrieval. We have to encode it into them with formal methods like IDEAS.It's a hard question because it's related to many questions that have been going on for a long time about AI, the "meaning of meaning", semantics vs syntax, types, set theory, categories, mereonomy, etc. I think now that we've got some of the "accidental" problems (e.g., when I had to write assembly language on green tablets or when we couldn't even run RDBMS' because they were too slow) behind us in computer science, we can start chipping away at some of these "essential" questions now. Depends on near-universal mathematics and science that all learn very similarly
