Grant o
Principal = … o
Resource = … o
Right = view … o
Right = extract … o
Right = sublicense
Transfer = view
Sublicensee →organization = Principal→organization
o Right = extract
Output
→Resource •
→Licence→”contains right”= {view} In this case the original licensee would have view and extract rights but could only
sublicense view to anyone, and sublicense extract to members of his own organization. Other restrictions could be placed on these rights through property conditions.
9.5.3.3.6 Spatial Temporal Conditions
A spatial condition may limit the spatial or temporal extent of the resource that the actions allowed by the right may address. The expression of a spatial or temporal or
spatiotemporal extent may be in any coordinate reference system or may cover multiple reference systems for subsets of the coordinates. The default CRS is WGS 84 Latitude-
Longitude the CRS used by GPS, and the default temporal reference system is Universal Time Zulu the TRS used by GPS.
The semantics of the condition shall be specified. The parameter that is restricted should be explicitly given. For example, a pure temporal condition might indicate but is not
restricted to one of the following:
• Restrict access to resource originally collected within the time limits.
• Restrict access to resource entered into the resource within the time limits.
• Restrict access to the resource to the time limits.
For example, a pure spatial condition might indicate but is not restricted to one of the following:
• Restrict access to resource collected from within these limits.
• Restrict access to users currently located within these limits.
9.5.3.3.7 Layer conditions
Layer conditions shall be used to limit what resource layers that can be used or modified in conjunction with a right. For resources, this shall subset the resource based on internal
layer structures. For processing rights, this shall determine what types of layers shall be processible by the software, possibly regardless of the underlying resource.

Page 64 of 131 For example, the right to use an image processing service might be restricted to “visible
light” layers. The right to use a navigation service might be restricted to road layers appropriately augmented with network connectivity associations. Some examples are
given below.
The Massachusetts Roads Maintenance Agency is given the right to modify the roads layer of a combined New England database, as long as the records modified are part of
Massachusetts road system, by the following grant form:
• Grant
o Principal = Massachusetts Roads Maintenance Agency
o Resource = Combined New England SDI
→Layer = Roads…
o Right = modify
Input
→location “is contained in” Massachusetts The Massachusetts Emergency Dispatch is given the right to use navigation services
against the roads layer of a combined New England database, as long as the records used are part sufficient for use by navigation systems, by the following grant form:
• Grant
o Principal = Massachusetts Emergency Dispatch
o Resource = Combined New England SDI
→layer = Roads
→“accepted use” = navigation
o Right = execute
Process
• → Compliance = URN:OGC:NAVIGATE
