Territorial, Provincial and Federal agencies which are actively
involved in collecting, preparing, analysing and distributing geochemical
information will be represented on the Subgroup to guide the development
of the data model, its science language, and quality controls and

the decisions and concerns of the Subgroup to their own organizations
and to represent fairly to the Subgroup the views of their organizations.
1. Overall guidance. The
Subgroup specifies the scope of activities for development and implementation
of the data model. The Subgroup provides authoritative statements
of the model's purpose, its intended use and users, and its relationships
with other specifications such as the Canadian Geospatial Data Infrastructure
(CGDI), the Open GIS Consortium (OGC), and other groups developing
Coordination of technical teams.
The Subgroup identifies functional goals for the data model in sufficient
detail that a technical team working towards each goal can accomplish
clearly specified tasks within one year. For each functional goal,
the Subgroup will identify the technical need, state the immediate
goals of the team, identify people who can work on the team, and
facilitate, evaluate, and disseminate the work of the team. Examples
of technical teams may include: conceptual data model design; scientific
terminology; software tool development; and policy evolution.
Publicity and organizational liaison.
The Subgroup works to publicize the model and its supporting products
in appropriate conventions, meetings, workshops, and publications.
The Subgroup provides information on its progress to the Canadian
Geoscience Knowledge Network through the Data Infrastructure Working
Group meetings, the National Geological Surveys Committee, and contributing
Communication and Support. The
Steering Committee facilitates public discussion and individual
guidance regarding both broad issues and technical details of concern
in the data model. These discussions and guidance are supported
by technical information exchange at the CGKN web site and the Geochemistry
Online documentation site. Members will actively solicit comments
and guidance from the technical experts whose interests they represent
to the Committee, and will respond regularly to that constituency.
co-leaders, one representing Federal agencies and the other the
Provincial and Territorial agencies will lead the Subgroup. GSC
management and the Committee of Provincial Geologists will appoint
the co-leaders, respectively. These leaders will act as the Stewards
for this data model and will:

as the official point of contact between the Subgroup and
agency will be responsible for maintaining its own database, including
the provision of the necessary computer systems to support it and
personnel to populate it. Funding will be sought from national programs
such as GeoConnections for support in developing common software
and documentation, and to support travel for regular Subgroup meetings
(two per year). Travel support will also be required so that Subgroup
members can actively participate in international activities related
to data model development, especially science language.
The subgroup will establish annual and longer term (3
year) plans to estimate funding requirements from member agencies
and from national programs.
The subgroup will meet via conference call regularly
(6-10 times per year), and face-to-face as needed. The Subgroup
will submit its annual plan to the CGKN secretariat for approval,
and will prepare a written report to the secretariat annually.
Technical teams are formed by the Subgroup to develop:
detailed functional specifications of the data model; software tools
and test?data meeting the specifications; terminology, and quality
control mechanisms. The work of the technical teams will be defined
specifically enough that the tasks can be accomplished within one
year. This requirement is meant to allow the membership of technical
teams to vary from year to year as needed by the teams and by the
organisations that employ the team members. Technical team members
are specialists in scientific or technological disciplines, and
usually the work of the team falls within the member's professional
