Issues in implementing ISO Issues in implementing ISO 1911519115

• To adequately describe data we need to To adequately describe data we need to use many ISO standards, e.g.use many ISO standards, e.g.– 19110: Feature cataloguing methodology19110: Feature cataloguing methodology– 19111: Spatial referencing by coordinates19111: Spatial referencing by coordinates

• No clear way to integrate information No clear way to integrate information defined by multiple parts of ISO 19xxx defined by multiple parts of ISO 19xxx standardsstandards– If there isn’t a standard XML DTD, the If there isn’t a standard XML DTD, the

information isn’t interoperableinformation isn’t interoperable
