The feature code data dictionary of CDB v3.0 is currently limited to the FACCs provided by the DIGEST 2.1 Feature Codes1. Users have expressed an interest in a broader feature code data dictionary, one which would embody most (if not all) of the feature codes encountered in the commonly used Geomatics standards. PROPOSED SOLUTION Feature Code Data Dictionary The Feature Code Data Dictionary has been extended to include Feature Codes from additional geomatics standards. A total of 635 new Feature Attributes have been added to the CDB Feature Code Data Dictionary; these new codes come from several commonly-used (U.S.) governmental geomatics standards. Note that when considering Feature Codes for inclusion into CDB, those Feature Codes that referenced time-variant features were excluded from consideration given that they fell outside the stated mandate of the CDB. Furthermore, Feature Codes that were redundant with CDB 3.0 were also excluded from consideration (i.e the CDB feature data dictionary already handled the Feature Code). The new Feature Codes have been assigned codes that use the same coding approach as used in the previous CDB specification (v3.0), namely a 5-digit FACC supplemented by a 3digit FSC. 1 Note that the CDB takes many of the DIGEST FACCs are supplemented with a sub-FACC to provide features with sub-categories. The CDB Specification provides sub-codes such AD010: Power Plant, AL015: Building, AL120: Missile Site, EC030: Trees, etc. 1 FACCFSC FSC Level 3 Level 2 Level 1 FACC A FACC-FSC Label FACC Concept Definition Origin Culture 15 015 000 AB015000 Incinerator A permanent structure used for the disposal of waste products by burning.

DGIWG FDD Dec 08 COMPATIBILITY CDB 3.1 offers 635 additional FACCs/FSCs to its Feature dictionary. These Feature Codes are supported by the DGIWG FDD and the ISO/IEC 18025 data dictionaries. The new Feature Codes use the same coding approach as used in the previous CDB specification (v3.0), namely a 5-digit FACC supplemented by a 3-digit FSC. Backward Compatibility Requirements: In order to be backward compatible, v3.1 CDB generation tools and v3.1 CDB client-devices must: a) Interpret all of the FACCs/FSCs of v3.0 plus the additional FACCs/FSCs proposed in v3.1 Forward Compatibility Requirements: In order to be forward compatible, v3.0 CDB generation tools and CDB client-devices must: a) Cope gracefully with the additional FACCs/FSCs (e.g. ignore them). A NOTE ON COMPATIBILITY Data does nothing in the absence of an interpreter (such as database generation tool or a client-device); as a result, the notion of backward and forward compatibility does not apply to the CDB itself, it only applies to software that reads or writes the CDB. Backward compatibility refers to the ability of a database generation tool or a client-device implemented to version n of the specification to accept a CDB compliant to version (n-1) of the specification. By transitivity, if version (n-1) is also backward compatible with version (n2), which in turn is backward compatible with version (n-3), then version n is backward compatible with the oldest version that is not backward compatible with its predecessor. Forward compatibility is the ability of a software program to gracefully accept input intended for a later version of itself and pick out the "known" part of the data. Forward compatibility is harder to achieve than backward compatibility because a software program needs to cope gracefully with an unknown future data format or requests for unknown future features. ALLOCATION OF ATTRIBUTES TO DATASET COMPONENTS PROBLEM DEFINITION Several inconsistencies wrt attributes to the CDB Dataset Components were found in version 3.0 of the CDB Specification. The errors were introduced due to the fact that the information regarding attributes appears in several areas of the CDB specification and is sometimes contradictory. Examples of such conflicting information include: a) Whether an attribute is instance-level and/or class-level b) Whether the usage of an attribute is mandatory vs optional c) The allocation of the Dataset Components to each attribute In v3.0 of the CDB specification, this information appears in nine distinct areas as follows: 1. section 5.3.1.2.2 Instance-level Attributes 2. section 5.3.1.2.3 Class-level Attributes 3. Table 5-27 and Table 5-28 in section 5.3.1.9 GSFeature Dataset 4. Table 5-32 and Table 5-33 in section 5.3.1.10 GTFeature Dataset 5. Table 5-35 and Table 5-36 in section 5.3.1.11 GeoPolitical Dataset Definitions 6. Table 5-38 and Table 5-39 in section 5.3.1.12 RoadNetwork Dataset 7. Table 5-42 and Table 5-43 in section 5.3.1.13 RailRoadNetwork Dataset 8. Table 5-46 and Table 5-47 in section 5.3.1.14 PowerlineNetwork Dataset 9. Table 5-50 and Table 5-51 in section 5.3.1.15 HydrographyNetwork Dataset PROPOSED SOLUTION Clarification regarding the Assignment of Attribution Schemas to each of the CDB Attributes A full clarification regarding the Assignment of Attribution Schemas to each of the CDB Attributes is provided in the addendum titled “Allocation of Attribution Schemas to Attributes” Clarification regarding the Usage of CDB Attributes In version 3.0, the usage guidelines for each attribute were confined to whether the attribute was mandatory or optional. Version 3.1 of the specification expands and clarifies this concept to the following four categories: Mandatory: A mandatory attribute is an attribute whose value must be provided for all of the features of a specified dataset, ie. a producer of CDB data (e.g. tools) is required to generate values for mandatory attributes. Consumers of CDB data (tools and/or simulator client-devices) can rely on the availability of mandatory attributes. A CDB with missing mandatory attributes is considered non-compliant by this Specification. Recommended: A recommended attribute is an attribute whose value should be provided for all of the features of a specified dataset. Consumers of CDB data (tools and/or simulator client-devices) can always rely on the availability of recommended attributes since the attribute value is either provided explicitly by the CDB or provided implicitly as a defaulted value. A CDB with defaulted recommended attributes is considered compliant by this Specification; however, the performance of one or more of the client-devices (commonly found on simulation devices) may be adversely affected. Optional: An optional attribute is an attribute whose value may (optionally) be provided for all of the features of a specified dataset. Consumers of CDB data (tools and/or simulator client-devices) cannot rely on the availability of optional attributes. A CDB with missing optional attributes is considered compliant by this Specification; however, the performance of one or more of the client-devices (commonly found on simulation devices) may be enhanced by including the optional attributes. Dependent: A dependent attribute is an attribute whose value depends on another attribute, be it mandatory, recommended, or optional. The attribute is considered mandatory if the attribute it depends on is mandatory. Likewise, the attribute is considered recommended if the attribute it depends on is recommended. Finally, the attribute is considered optional if the attribute it depends on is optional. The following table summarizes the evolution of the CDB attribute usage from v3.0 to v3.1. Note that in v3.1, the Attribute generation process is less onerous on CDB generation tools because many of the attributes that were prescribed as mandatory have now been reduced to either “recommended” or to “optional”.

Legend Not applicable to v3.0 M R O D Attribute usage is mandatory Attribute usage is recommended Attribute usage is optional Attribute usage is mandatory but is dependent on prescribed criteria Attribute is deprecated in v3.1 (backward compatible until v4.0) Clarification of the Allocation of CDB Attributes To Dataset Components The CDB Specification limits the applicability of each of the CDB attributes to certain Datasets Components. This approach primarily helps to reduce the number of columns (hence reduces the size) of the *.dbf instance- , class-level and now to the extended-level attribution files (see addendum titled Additional Attributes). To this end, v3.1 of CDB specification provides a comprehensive table which assigns each of the CDB attributes to the applicable Dataset Components; the table also provides information to indicate whether the attribute is mandatory, recommended, optional or dependent on other criteria.

In order to be backward compatible, v3.1 CDB generation tools and v3.1 CDB client-devices must: a) When reading, v3.1 CDB generation tools and client-devices must handle the case where some attributes are no longer present in some dataset components due to the less stringent usage requirements of CDB v3.1 b) When writing, CDB generation tools are permitted to relax usage requirements to those specified in v3.1 Backward Compatibility Requirements – CASE II: v3.1 promotes attribution usage requirements from a “not used” status to either “optional” / “recommended” status OR from a “optional” status to a “recommended” status. In order to be backward compatible, v3.1 CDB generation tools and v3.1 CDB client-devices must: a) When reading, v3.1 CDB generation tools and client-devices must handle the case where some attributes are now present in some dataset components due to the more stringent usage requirements of CDB v3.1 b) When writing, CDB generation tools are required to generate the attribution to the more stringent usage requirements specified in v3.1 Backward Compatibility Requirements – CASE III: There are two cases where an attribute that was “optional” or “not used” in CDB v3.0 has been upgraded to “mandatory”. They are: a) The APFN attribute for the AirportNetwork Lineal component of the RoadNetwork dataset is upgraded to Mandatory. This was a specification omission in the CDB v3.0 b) The JID attribute for the HydrographyNetwork Lineal Figure Pt component of the Hydrography dataset is upgraded to Mandatory. This was a specification omission in the CDB v3.0 In order to be backward compatible, v3.1 CDB generation tools and v3.1 CDB client-devices must: a) When reading, v3.1 CDB generation tools and client-devices must be able to process the APFN and JID attributes in conformance to the attribute usage requirements specified in v3.1. b) When writing, CDB generation tools must now generate the APFN attribute for the AirportNetwork Lineal component of the RoadNetwork and JID attribute for the HydrographyNetwork Lineal Figure Pt component of the Hydrography dataset. Forward Compatibility Requirements: Since v3.0 attribution usage requirements are more onerous than in v3.1, v3.0 CDB generation tools and CDB client-devices are by default forward compatible with v3.1 CDB A NOTE ON COMPATIBILITY Data does nothing in the absence of an interpreter (such as database generation tool or a client-device); as a result, the notion of backward and forward compatibility does not apply to the CDB itself, it only applies to software that reads or writes the CDB. Backward compatibility refers to the ability of a database generation tool or a client-device implemented to version n of the specification to accept a CDB compliant to version (n-1) of the specification. By transitivity, if version (n-1) is also backward compatible with version (n2), which in turn is backward compatible with version (n-3), then version n is backward compatible with the oldest version that is not backward compatible with its predecessor. Forward compatibility is the ability of a software program to gracefully accept input intended for a later version of itself and pick out the "known" part of the data. Forward compatibility is harder to achieve than backward compatibility because a software program needs to cope gracefully with an unknown future data format or requests for unknown future features.
