Motivation • RFC 4776 asks for civic address considerations documents for individual countries • Ensure interoperability, PSAPs certainly want to rely on finding location information types in a defined element – Never confuse a PSAP agent • Guideline for usage of PIDF-LO elements to avoid misinterpretations – Consistent (national) mapping scheme required

What is in the draft? • Mapping of Austrian civic address elements to existing PIDF-LO elements (incomplete for now) • Problem statement house numbers – Mapping options • Address codes – Address URN idea

Problem: House Numbers „Hauptstrasse 1 a - 5 a Block 1 b Haus 2 c Stiege 1“ “Lazarettgasse 13 A - 13 C” • PIDF-LO knows just two elements for house numbers – HNO: house number (numeric part only) – HNS: house number suffix • Statistik Austria knows 20 data fields related to the house number – Categories: estates, buildings and usable units • Even revised-civic-lo does not solve this problem

Mapping to PIDF-LO • Most elements can be easily mapped – but the most important one (house number) not • Options to map house number – Omit all address parts that do not fit in • Certainly unacceptable (incomplete address) – Violate intended purpose of element (re-definition) • Nobody likes that, but it would work… – Concatenate elements: • Loss of information, no reversal possible • Mixture with previous option possible… – New civic address elements? • “HN 1”. . . “HN 20” similar to “A 1” … “A 6”? • Definition of “HN” mappings local matter

Austrian Address Codes • Additional code element • Codes by Statistik Austria – – Address code (“Addresscode”) Address subcode (“Addresssubcode”) Object code (“Objektnummer”) Usable unit code (“Nutzungseinheitenlaufnummer”) • Uniquely identify the civic location – Transport only the “A 1” + codes, and look up address?

Next Steps • How to proceed with this document? – Is this useful? – Keep as individual or make WG item? • This is just one country – Generic template for such “civic address considerations”? – In WG scope? • Questions? alexander. mayrhofer@nic. at karlheinz. wolf@nic. at

Sample Addresses • Lazarettgasse 13 A - 13 C – Street: Larzarettgasse – House Number 13 A-13 C • Mapping to PIDF-LO?

Sample Addresses • Wiedner Hauptstrasse vor 1 – 1 A – Street: Wiedner Hauptstrasse – House Number: vor 1 – 1 A • Mapping to PIDF-LO?
