Title:
Extension of temporal operators to add AnyInteracts operator

Use one of the following categories:
F (Critical correction)
A (corresponds to a correction in an earlier
release)
B (Addition of feature),
C (Functional modification of feature)
D (Editorial modification)
Detailed explanations of the above categories can
be found in the TC Policies and Procedures.
Reason for change:
Feedback from OWS6-AIM on the use of FES2.0 temporal operators
Summary of change: In FES 2.0 there is currently no standard operator to support an ‘any interaction’
type query on a time period. The workaround is very verbose and requires 4
negated temporal operators:
NOT Before: (i.e. end time < start time)
NOT Meets: (i.e. end time = start time)
NOT After: (i.e. start time > end time)
NOT MetBy: (i.e. start time = end time)
To shortcut the above query and to reduce complexity this CR proposes the
creation of the following additional TemporalOperator:
Consequences if
not approved:
Over verbose implementation and unnecessary complexity
Clauses affected:
7.9 Temporal Operators
Other specs
Affected:

X Other core specifications

Status
Disposition
The temporal operators of FES2.0 are aligned to ISO19108, for consistency a
change request to ISO19108 may need to be raised

contain pop-up help
information about the
field that they are closest
to.
Obtain the latest version for
the release of the
specification to which the
change is proposed. Use
the MS Word "revision
marks" feature (also
known as "track
changes") when making
the changes. All Open
GIS specifications can be
downloaded from the
OGC server under

it) into the specification just
in front of the clause
containing the first piece of
changed text. Delete those
parts of the specification that
are not relevant to the
change request.
