Maintenance of the Standard
Section 7 of the On-line Course:
Learning the Cadastral Data Content Standard
Section 7 describes current information on how to propose
and track changes to the Cadastral Data Content Standard.
Topics in Section 7:
The Cadastral Data Content Standard Maintenance Plan is described
in section 1.6 of the Standard. The FGDC Subcommittee on Cadastral Data
will manage the maintenance of the Standard. The maintenance process will
result in updates to domains of values as needed to meet users' needs.
Changes made to any Standard, after the Standard has been
accepted and implemented, can lead to very complex database changes and
re-designs for each office which has implemented the Standard in a physical
The sections below summarize the Maintenance Plan. To

Plan. Or, to download a copy of the Maintenance Plan from
the Fairview Industries Web site, go to Fairview's
ftp page for cadastral information.
Requests related to the Cadastral Data Content Standard
may be for a variety of actions and may come from a variety of sources.
The Subcommittee is actively soliciting requests from active cadastral
standard testing and development projects. Requests will be encouraged
from published papers, presentations, Internet queries, email, or any other
source. Members of the Subcommittee may submit requests also.
The Subcommittee has identified the following types of
requests that may be submitted.
See the Cadastral Data Content Standard.
Discrepancy Report - A discrepancy report indicates that
the standard incorrectly represents cadastral data, has an error in a relationship,
has an incorrect entity, or has an incorrect attribute within an entity.
Statement of Need - A statement of need indicates that the
standard needs additional explanatory material, needs an additional value
added to a domain of values, or some other statement for augmentation of
Explanatory Materials - A request for explanatory materials
is additional education about the intent or meaning of an entity, attribute,
relationship, or domain value in the Standard.
Other Requests - Any other request for information or presentations
falls into the other request category. This may include but is not limited
to typographical or editorial corrections.
An agency or office engaged in a physical implementation
of the Standard may find a need to add their own information that is not
included in the Standard. It is foreseen that each agency would make their
own additions for their purposes alone. If they then consider that their
additions would be pertinent to the Federal Standard, then they would recommend
their additions to the Subcommittee on Cadastral Data.
The Cadastral Maintenance Subgroup will review all requests
on a quarterly basis. The reviews may occur more frequently if there are
a large number of requests, but at least once per quarter, at the beginning
of the quarter, the Cadastral maintenance Subgroup will review requests.
Requests for change to the standard must contain:
To request maintenance on the Cadastral Data Content Standard,

Date of Request
Type Of Maintenance
Page Number Or Section Reference
Title Of Request For Maintenance
Description of the Request Maintenance
Page or Subject Area Reference
On a regular basis, which will be monthly in the first year,
the Request Coordinator will compile the requests, organize them into a
database, conduct a preliminary analysis on a potential response or a suite
of responses, and forward the requests on to the Cadastral Maintenance
The Subcommittee has a contact database for tracking requests.
Each request receives a tracking number when it is entered into the database.
The dates and actions related to the request are tracked through the request's
life cycle. The database will track significant events.
Results will be developed into a frequently asked questions
(FAQ) list that will be posted to the cadastral Internet sites.
Version Control of the Standard
Current practice is to indicate Versions of the Standard
by their date.
Change Management Process
Changes to the Standard will follow the Federal Geographic
Data Committee (FGDC) Standard Working Group (SWG) procedures for standard
modification. For changes that involve clarification, additional explanatory
material, or grammatical construction, the standard revision would not
affect implementation sites and could be made without a full review of
the entire standard.
If the changes are substantial or could impact an implementation
of the standard, than the revisions would go through the same steps as
the original standard review in the FGDC Standard Development Process.
Changes Currently Proposed
To see examples of proposed changes to the Standard, go to
the FGDC Cadastral
Standard Maintenance page.
Examples of Changes

page for cadastral information.
