1 Metadata Existing Guidelines ADQ AIXM Workshop 10 December 2013 Eduard Porosnicu EUROCONTROL DSR/CMN/IM Metadata allows Data to be found Starts interoperability Decision making based on Quality Relevance Time Geography 2

2 INTEROP Regulation, ADQ IR, EUROCONTROL Specifications Interoperability Regulation (552/2004) in the context of Single European Sky (SES) objective of ensuring the interoperability of the European ATM Networ Aeronautical Data Quality Implementing Rule (ADQ IR) No 73/2010 requirements on the quality of aeronautical data & information EUROCONTROL Specifications For ADQ1 Electronic AIP (eaip) Data Quality Requirements (DQR) Data Assurance Levels (DAL) Aeronautical Information Exchange (AIX) Data Origination (DO) 3 INSPIRE Directive and IRs INSPIRE Directive create a European Union (EU) spatial data infrastructure sharing of environmental spatial information among public sector organisations better facilitate public access to spatial information across Europe Implementing Rules on: Metadata Data Specifications Network Services Data and Service Sharing Monitoring and Reporting Lots of (non-binding) Guidance material D2.3 D2.5 4

3 Aviation Metadata 1. Requirements: 2. Guidance 5 OGC Requirements for aviation metadata Date: 28-March-2011 OpenGIS Discussion Paper Released document, not just a draft! AIXM 5.1 TrainingAIS-AIMSG-#4 6

4 Requirements 7 Requirements example: Identification Resource Title This is a characteristic, and often unique, name by which the resource is known. The value domain of this metadata element is free text. [Source: INSPIRE IR (1.1)] Resource Abstract This is a brief narrative summary of the content of the resource. The value domain of this metadata element is free text. [Source: INSPIRE IR (1.2)] Resource Language The language(s) used within the resource. The value domain of this metadata element is limited to the languages defined in ISO [Source: INSPIRE IR (1.7)] 8

5 Requirements example: Data Quality and Validity Lineage This is a record on the process history and/or overall quality of the aviation data set. Where appropriate is may include a statement whether or not the data set has been validated or quality assured. In particular this metadata element shall record: The name of the organization or entity performing the function; The function performed. See section 7.1 for the options; and The date and time of operation.

10 Summary ADQ Metadata Requirements -> AIX Specification Supported by the OGC Requirements for aviation metadata Implementation guidelines in relation with AIXM 5.1 Supported by the OGC Guidance on the Aviation Metadata Profile In practice AIXM 5.1 XSD includes the ISO XML Schema To be used in particular at data set level AIXM 5.1 XSD includes metadata elements at property level Effective start and effective end [AIX-MD-07] Coordinate reference system [AIX-MD-08] [AIX-MD-09] Accuracy of the data [AIX-MD-10] Resolution of the data is implicit [AIX-MD-11] ADQ Implementation Support Cell 19
