# Package org.opengis.cite.iso19142.joins

package org.opengis.cite.iso19142.joins
This package includes tests for join queries. Servers that implement join queries shall implement an inner join; that is, only features that satisfy the join condition(s) shall be included in the result set.

Three conformance classes are distinguished; the corresponding service constraints are shown in parentheses:

- Standard joins (ImplementsStandardJoins)
- Spatial joins (ImplementsSpatialJoins)
- Temporal joins (ImplementsTemporalJoins)
