Environmental Data Coding Specification (EDCS)

The EDCS Problem Space

• The SEDRIS Data Representation Model provides
  the form, organization, and inter-relationships
  of environmental data
• The Spatial Reference Model provides location
  information
• The EDCS is the data dictionary

Provide for shared understanding of the semantic
that should be associated with environmental
data, regardless of its representation or
location, including data describing air, land,
sea, space, or atmospheric objects used in live,
virtual, or constructive simulations in
entertainment, training, C4I, or mission
rehearsal applications

What About Extant Dictionaries?
DIGEST FACC is a prominent example that is widely
used, promulgated by an international body, and
recognized as a NATO standard But... --
Designed to address the mapping, charting and
geodesy domain - what of space, oceans,
atmosphere, entities ? -- Attribution is
closely tied to specific units - what happens
when length should be measured in
millimeters? -- Inseparable from a specific
organizational scheme - what about organization
for novel domains?

EDCS Design
The EDCS started with existing dictionaries (e.g.
FACC) to construct a new system, appropriate for
the larger domain of applicability and engineered
to overcome the limitations that have thus far
come to light
EDCS Dictionaries (from ISO Committee
Draft 2) EDCS Classification Dictionary

Enumerant Dictionary (EEC) EDCS Attribute Value
Metadata Dictionary (EMC) EDCS Unit Dictionary

Organizational Schema Dictionary (EOC) EDCS
Group Dictionary (EGC)

EDCS PDG Purpose

• To review the EDCS technologies and the
  associated software implementation
• To provide comments, modifications,
  improvements for incorporation into the ISO/IEC
  standard
• Once the results are satisfactory to SISO, to
  recognize the EDCS as a formal SISO product,
  recommending and encouraging its use within the
  MS community -- That product will reference
  appropriate ISO/IEC specification standards
• To encourage and guide the development of
  utilities (software, mapping documents, use
  guides, etc.) that will enhance usability of the
  EDCS

Why a SISO Product?

• Leverage an extant SEDRIS technology across a
  broader domain than environmental data
  representation and interchange
• Broadened domain of interest includes, e.g.
• Any MS data including environmental information
• Non-environmental runtime (e.g. entity enums)
• Environment runtime (e.g. SOM development)
• To be accomplished by utilizing the formal SISO
  product nomination/development process
• Reference products based on an existing body of
  standards work with ISO
• Fast-track efforts within SISO to develop
  guidance products to standardize Reference
  Implementations

SISO Contribution

• SISO Product would add value to the ISO/IEC
  specification standards in two fashions
• Formalizing the recommended uses of the
  specification standards within the MS community,
  including use cases
• Extending (or refining) the specification
  standards for use within the MS community
