fgdc entity-attribute information not supported by mdJson/mdTranslator

[stansmith907]

Working though the FGDC entity-attribute section (5) I found much of the information not supported by our mdTranslator and mdJson schemas. This is likely because we patterned mdTranslator dataDictionary on SQL table creation requirements. Also, ISO implements data dictionaries using FC_FeatureCatalogue which optimistically is a poor fit.

FGDC has additional fields that could enrich our description of entities and attributes that we may wish to adopt even if we can only move a few of them to ISO metadata records. If all these fields were added we could accurately describe ASCII CSV or tabular datasets in addition to SQL and spreadsheets.

• attribute definition external reference (is in FC_FeatureCatalogue)
• attribute unit measurement resolution
• attribute measurement frequency
• attribute {begin date / end date}n
• attribute accuracy (likely in ISO 19157)
• case sensitive (Boolean)
• field width
  and others that could be added to entity
• entity definition external reference (is in FC_FeatureCatalogue)
• missing value code
• field separation character
• number of header lines
• quote character [ single | double ]
  and others that could be added to domain
• domain definition external reference (is in FC_FeatureCatalogue)
• unrepresentable domain (text description)

Of those, unrepresentable domain is used quite a bit.. External references are used occasionally in terms of citing the source. The rest I have not seen used. ISO made a confusing mess out of data dictionary, IMO.
