A proposal for a new work item (includingproposals for amendment or revision of an existing standard) within the scope of an existing technical committee orsubcommittee shall be submitted to the secretariat of that technical committee or subcommittee with a copy to the CentralSecretariat and, in the case of a sub-committee, a copy to the secretariat of the parent technical committee. The proposal willbe circulated to the P-members of the technical committee or subcommittee for voting, and to the O-members for information.The proposer may be a member body of ISO, the secretariat itself, another technical committee or subcommittee, anorganization in liaison, the Technical Management Board or one of the advisory groups, or the Secretary-General. Guidelinesfor proposing and justifying a new work item are given in the ISO/IEC Directives (part 1, annex Q) (see extract overleaf).
The proposal (to be completed by the proposer)
Title of proposal (in the case of an amendment or revision, or a new part, of an existing standard, show the standardnumber)
Geographic information - Profile - FACC Data Dictionary
Scope (as defined in 6.2.1 of part 3 of the ISO/IEC Directives)
This International Standard is a profile. It is based on rules and methodsdefined in ISO CD 19110 (15046-10) Geographic information – Feature cataloguingmethodology, in the context of DGIWG. It defines a Data Dictionary and includesthe definition of Features and Attributes only, which may be of use to the widerinternational community.
Purpose and justification (attach a separate page as annex, if necessary)
See annex
Target date (indicate the date by which the availability of the 30 April 2001International Standard is considered to be necessary)
Relevant documents to be considered
ISO 19110 (15046-10) Geographical information - Feature catalogue methodology,
NATO STANAG 7074 DIGEST 2.0, Part 4 FACC, 1997
Relationship of project to activities of other international bodies
The DGIWG has maintained the FACC Data Dictionary as part of the DIGEST standardfor many years. FACC is used as part of a Feature Catalogue within the context ofProduct Specifications for many DIGEST compatible products. The DGIWG and IHOhave also worked to harmonize the FACC Data Dictionary with the Data Dictionarydefined in the IHO S-57 "Object Catalogue".

Elements to be clarified when proposing a new work item (new standard)
Title
Indicate the subject matter of the proposed new standard.
Scope
Give a clear indication of the coverage of the proposed new work item and, if necessary for clarity, exclusions.
Purpose and justification
Give details based on a critical study of the following elements wherever practicable.
a) The specific aims and reason for the standardization activity, with particular emphasis on the aspects of standardizationto be covered, the problems it is expected to solve or the difficulties it is intended to overcome.
b) The main interests that might benefit from or be affected by the activity, such as industry, consumers, trade,governments, distributors.
c) Feasibility of the activity: Are there factors that could hinder the successful establishment or general application of thestandard?
d) Timeliness of the standard to be produced: Is the technology reasonably stabilized? If not, how much time is likely to beavailable before advances in technology may render the proposed standard outdated? Is the proposed standard required asa basis for the future development of the technology in question?
e) Urgency of the activity, considering the needs of other fields or organizations. Indicate target date and, when a series ofstandards is proposed, suggest priorities.
f) The benefits to be gained by the implementation of the proposed standard; alternatively, the loss or disadvantage(s) if nostandard is established within a reasonable time. Data such as product volume or value of trade should be included andquantified.
g) If the standardization activity is, or is likely to be, the subject of regulations or to require the harmonization of existingregulations, this should be indicated.
If a series of new work items is proposed, the purpose and the justification of which is common, a common proposal may bedrafted including all elements to be clarified and enumerating the titles and scopes of each individual item.
Relevant documents
List any known relevant documents (such as standards and regulations), regardless of their source. When the proposerconsiders that an existing well-established document may be acceptable as a standard (with or without amendments) indicatethis with appropriate justification and attach a copy to the proposal.
Cooperation and liaison
List relevant organizations or bodies with which cooperation and liaison should exist.
Preparatory work
Indicate whether the proposer or the proposer's organization is prepared to undertake the preparatory work required for thenew work item.

Annex to Purpose and justification
The DGIWG has worked with ISO/TC 211 since the establishment of the ISO TechnicalCommittee, with respect to the development of the ISO/TC 211 suite of standards. Since thebeginning, the intent of DGIWG has been to develop profiles of the ISO GeographicInformation standards that correspond to the components of the DIGEST standard. DGIWGhas been active in the development of the TC 211 standards to ensure that these standardsare capable of being used to develop profiles corresponding to the DIGEST standard. Thestructure of DIGEST and the FACC Data Dictionary are described in the ISO TR 19120Geographic information - Functional standards.
The FACC Data Dictionary is the first of the parts of DIGEST to be proposed as an ISO/TC211 profile. The intent is that FACC will also retain its DIGEST status as part of STANAG7074 and that the profile will be maintained by DGIWG.
DGIWG has worked closely with the International Hydrographic Organization (IHO), also aClass A Liaison with TC 211, with respect to the relationship of the FACC to the IHO S-57Object Catalogue. A direct conversion has been defined at the feature and attribute level. Inaddition, a conversion has been developed between the DNC product specification and theIHO ENC product specification for Nautical Charts.
The DIGEST FACC has been completely reformatted and updated to align with the rulesdescribed in the TC 211 Committee Draft standard CD 19110 Geographic information –Feature cataloguing methodology, with respect to that part addressing a data dictionary.
