The registry is then referenced by other protocols that need a common set of location terms as protocol constants. Examples of location terms defined in this document include aircraft, office and train station. Table of Contents 1. Introduction . . . . . . . . . . . . . . . . . . . . . . . . . 3 2.

Introduction This document creates a registry for location type tokens. We anticipate that the network, through configuration or management protocols, tells a mobile device what kind of location it finds itself in. The device and associated software can then tailor its behavior to the environment. For example, this document defines the terms "classroom", "place-of-worship" and "theater". A considerate owner of a cell phone might program the device to switch from ringer to vibrate mode in such environments. Just knowing the geographic location, be it as civic (street address) or geospatial coordinates would generally not allow the device to make a similar decision. Naturally, the number of descriptive terms for physical environments is almost unbounded. This registry tries to identify common terms that are likely to be useful for communications devices and for controlling and guiding communication behavior. The terms roughly correspond to the level of details of location descriptions and icons found on geographic maps, for example, and are meant to be in common use across a variety of cultures and countries. The registration process described in the IANA Considerations section allows to extend this list as needed, while aiming to prevent an unnecessary explosion in the registry. The use of tokens, i.e., protocol constants, makes it easier to build systems across multiple languages. A user interface can readily translate a finite set of tokens to user-appropriate textual or iconic representations. Protocols using this registry are encouraged to provide additional mechanisms to accommodate location types not currently registered via free-text fields with appropriate language and character set labeling. The terms defined in this registry do not attempt to provide a hierarchy of location descriptions, except in certain special cases. For example, the term "restaurant" is defined to include the term "cafe" and the term "public" encompasses a range of descriptors, as noted below. The registry makes these more generic terms available as often the more detailed distinctions may not be available, or privacy concerns suggest the use of less precise terms that are still sufficient to guide communications behavior or evaluate the source of a phone call or message, say. In many cases, a location might be described by multiple terms that apply at the same time. For example, the combination of "restaurant" and "airport" is immediately recognizable. This registry makes no attempt to limit the number of terms that can be used to describe a single place or to restrict what combinations are allowed, given that there are few combinations that are physically impossible. Common sense is probably a better guide here; the authors would not want to rule out creative business models such as combinations of "parking" and "restaurant" or "bar" and "hospital". The number of terms that can be used within the same protocol element is left to the protocol description. This document does not describe how the values of the registry are to be used, as this description is provided by other documents. For example, ,, describes a options for carrying civic address information, including the place-type attributes listed in this document, using the Dynamic Host Configuration Protocol (DHCPv4 and DHCPv6). A usage for RADIUS is described in ,, where this information is conveyed from the RADIUS client to the RADIUS server. Rich presence (RPID )) also utilizes the values of the location type registry. 2. Terminology The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in . 3.

IANA Considerations This document creates new IANA registries for location types as listed in Section 3 starting with 'aircraft' and finishing with 'watercraft'. Following the policies outline in RFC 2434 , new tokens are assigned after Expert Review by the IETF GEOPRIV working group or its designated successor. The same procedure applies to updates of tokens within the registry and to deleting tokens from the registry. There are no restrictions regarding the update of location-type values in the registry. The expert review should be guided by a few common-sense considerations. For example, tokens should not be specific to a country, region, organization or company, should be well-defined and should be widely recognized. To ensure widespread usability across protocols, tokens shouldMUST follow the character set restrictions for XML Names.Names . Each registration must include the name of the token and a brief description similar to the ones offered in for the initial registrations contained this document: Token Identifier: Identifier of the tokentoken. Description: Brief description indicating the meaning of the token.token, including one or more examples where the term encompasses several more precise terms. Note that the usage of these tokens is not limited to XML and the 'Token Identifier' is the XML element content and not the XML element name. 5. Internationalization Considerations The location-type values listed in this document MUST NOT be presented to the user. The values therefore have the characteristic of tokens/tagstokens or tags and no internationalization support is required. 6. Security Considerations This document defines a registry for location types and as such does not raise security issues. 7. Acknowledgements We would like to thank V. Gurbani, P. Kyzivat and J. Rosenberg for their work on RPID  which lead to the location types listed in this document. Many thanks to Allison Mankin for her guidance. Rick Jones pointed us to the Global Justice XML work (see http://it.ojp.gov/jxdm/) that helped us to add more values to the location registry. During the IETF last call, Harald Tveit Alvestrand, Frank Ellermann and Sam Hartman provided useful feedback. David Kessens helped to tighten up many of the defintions. Some of the definitions are derived from the Merriam-Webster Online Dictionary. 8.
