Notation InterchangeFileFormat NIFF is a music notation fileformat used primarily for transferring music notation between different scorewriter s. The NIFF project was started in February 1994 to create an open format that would allow exchange of music between various scanning Music OCR , editing and typesetting programs. The project was sponsored by several music notation software publishers. The NIFF format itself is based upon RIFF Fileformat RIFF Resource InterchangeFileFormat , a file structure provided by Microsoft, in which data is divided into Lists, Chunks and Tags. Almost all data in a NIFF file are optional. The level of detail contained can range from just the pitch and timing akin to MIDI to a precise page layout, embedded graphics and embedded MIDI information. Though detailed and comprehensive, the standard never really caught on except for limited interchange between music OCR software and scorewriting software. Three of the music OCR programs in widespread use PhotoScore, SharpEye, and SmartScore export NIFF files. NIFF is now considered obsolete mainly due to the MusicXML format. As of February 2006 the NIFF project web site has been closed. The NIFF SDK is available at the http www.music notation.info en formats NIFF.html The NIFF SDK Archive for educational usage.

About Requirements InterchangeFormat RIF ReqIF Rif Expand German date June 2011 RIF ReqIF Requirements InterchangeFormat is an Extensible Markup Language XML fileformat that can be used to exchange requirements, along with its associated metadata, between software tools from different vendors. The requirements exchange format also defines a workflow for transmitting the status of requirements between partners. Although developed in the automotive industry, ReqIF is suitable for lossless exchange of requirements in any industry. History In 2004, HIS Herstellerinitiative Software a consortium of German automotive manufacturers, defined a generic requirements interchangeformat called RIF. The format was handled over in 2008 to ProSTEP iViP e.V. for further maintenance. A project group responsible for international standardization further developed the format and handed over a revised version to Object Management Group OMG as Request for Comment in 2010. As the acronym RIF had an ambiguous meaning within the OMG, the new name ReqIF was introduced to separate it from the W3C s Rule InterchangeFormat . In April 2011, the version 1.0.1 of ReqIF was adopted by OMG as a formal specification OMG Document Number formal 2011 04 02 .

SAIF Dataset SAIF has two major components that together define SAIFtalk. The first is the Class Syntax Notation CSN , a data definition language used to define a dataset s schema. The second is the Object Syntax Notation OSN , a data language used to represent the object data adhering to the schema. The CSN and OSN are contained in the same physical file, along with a directory at the beginning of the file. The use of ASCII text and a straightforward syntax for both CSN and OSN ensure that they can be parsed easily and understood directly by users and developers. A SAIF dataset, with a .saf or .zip extension, is compressed using the zip archive format. Schema Definition SAIF defines 285 classes including enumerations in the Class Syntax Notation, covering the definitions of high level features, geometric types, topological relationships, temporal coordinates and relationships, geodetic coordinate system components and metadata.

PFIF was designed to enable information sharing among governments, relief organizations, and other survivor registries to help people find and contact their family and friends after a disaster. Overview PFIF is extended from XML . It consists of person records, which contain identifying information about a person, and note records, which contain comments and updates on the status and location of a person. Each note is attached to one person. PFIF defines the set of fields in these records and an XML based format to store or transfer them. PFIF XML records can be embedded in Atom standard Atom feeds or RSS feeds. PFIF allows different repositories of missing person data to exchange and aggregate their records. Every record has a unique identifier, which indicates the domain name of the original repository where the record was created. The unique record identifier is preserved as the record is copied from one repository to another. For example, any repository that receives a copy of a given person can publish a note attached to that person, and even as the note and person are copied to other repositories, they remain traceable to their respective original sources.

Abbreviated and regularly referred to as AMIS , the Audio Messaging Interchange Specification is a standard that allows the transmittal of intact voice mail messages between voice mail systems of different vendors allowing a user to forward a voice mail message to a user on a different voice mail system in a different geographic area, or conceivably, at a different company . Developed in 1992, AMIS saw its heaviest use prior to the wide scale adoption of e mail, as it was the fastest way to get urgent or time sensitive messages to large numbers of people e.g. A sales team with a broadcast message . Technical background AMIS is completely in band and analog, meaning that the control commands to indicate who the message is from, the time received and from mailbox or caller ID information is all sent as a series of DTMF Touch tone digits along with the message itself, which is transmitted played and re recorded by the target system in real time. Routing of messages is typically achieved through dedicated AMIS Trunk line trunks which are just unpublished phone numbers or back doors into a voice mail system, set up to receive AMIS messages. A voice mail system, on receiving a message addressed to mailbox it did not handle, would initiate an AMIS call to the target voice mail system and relay the message information along with the message itself. The target user could also reply to the message and the process would repeat in reverse. Current Use AMIS is still used in larger corporate environments to transfer voice mail messages between geographically separate offices, however, e mail and unified messaging which allows forwarding of voice mail messages via email is rapidly supplanting this purpose. It is supported by most major voice mail systems manufacturers IBM , Nortel , Lucent , Toshiba , Siemens , and Cisco among many others . The AMIS standard was first published in 1992 by the Industry Information Association. References reflist http www.cisco.com en US docs voice ip ... more details

XMA is the native Xbox 360 compressed audioformat, based on the Windows Media Audio WMA Pro architecture. Implementation The Xbox 360 system Southbridge computing Southbridge contains a full silicon implementation of the XMA decompression algorithm, including support for multichannel XMA sources. XMA is processed by the south bridge into standard PCM format in RAM. All other sound processing sample rate conversion, filtering, effects, mixing, and multispeaker encoding happens on the Xenon CPU. The lowest level Xbox 360 audio software layer is XAudio, a new API designed for optimal digital signal processing. The Cross platform Audio Creation Tool XACT API is also supported, along with new features such as conditional events, improved parameter control, and a more flexible 3D audio model.
