    Open Supervised Device Protocol (OSDP) Version 2.1.7 Communication Protocol for Peripheral Devices with Data Security Extension Copyright 2015 Security Industry Association DRAFT July 2015
    Draft Open Supervised Device Protocol (OSDPv2.1.7) Foreword This document, OSDPv2.1.7, is maintained by the SIA Standards Access Control and Identity Subcommittee. As with many specifications, SIA anticipates that there may be questions, interpretations, and extensions that may arise when using this specification. Please send all correspondence of this nature to osdp@siaonline.org. This address will be monitored by SIA staff and all correspondence will be forwarded to the attention of the SIA Standards Access Control and Identity Subcommittee. Supporting documents are also available through SIA that offer application specific guidance for common and uncommon uses of the OSDP specification. The SIA OSDP Profile document is a compendium of common use cases and the core SIA OSDP Messages in addition to Application and Manufacturer Specific Messages required to achieve OSDP conformance for a particular use case. The SIA OSDP Application Specific Messages Document, is a continuously updated repository of messages that have been presented to and accepted by the SIA OSDP WG as a complement to the core messages of this specification. Application Specific Messages that appear in the SIA OSDP Application Specific Messages Document have been determined to add new and actionable OSDP functionality by at least three vendors in the OSDP Working Group. SIA also hosts a listing of Manufacturer Specific messages. These messages have been submitted for use by the SIA OSDP community, but have not yet been accepted as part of an official Application Specific message.
