* STEP Physical File, ISO 10303-21 data encoding standard

* ISO 10303-21 ( Part 21, a very common ' part ' of STEP )

* IFC-SPF is a text format defined by ISO 10303-21 (" STEP-File "), where each line typically consists of a single object record, and having file extension ". ifc ".

The format of a STEP-File is defined in ISO 10303-21 Clear Text Encoding of the Exchange Structure.

ISO 10303-21 defines the encoding mechanism on how to represent data according to a given EXPRESS schema, but not the EXPRESS schema itself.

* The first edition of ISO 10303-21: 1994 had some bugs, which were corrected by a Technical Corrigendum.

* The second edition ISO 10303-21: 2002, including all the fixes and extensions for several data sections.

The NIST STEP Class Library is a public domain implementation of ISO 10303-21 ( ASCII data exchange files ),-22 ( SDAI ),-23 ( C ++ SDAI binding ) using ISO 10303-11: 1994.

VariCAD support the ISO industrial product data exchange format STEP / STP.

The functionality of GKS is wrapped up as a data model standard in the STEP standard, section ISO 10303-46.

* STEP AP210: ISO 10303-210, Electronic assembly interconnect and packaging design, first edition 2001, second edition 2008 ( to be published )

After the initial release of STEP ( ISO 10303 ) in 1994, interest in further development of IGES declined, and Version 5. 3 ( 1996 ) was the last published standard.

* STEP ( ISO 10303 )

STEP is developed and maintained by the ISO technical committee TC 184, Automation systems and integration, sub-committee SC 4, Industrial data.

Like other ISO and IEC standards STEP is copyright by ISO and is not freely available.

STEP is closely related with PLIB ( ISO 13584, IEC 61360 ).

In 1994 / 95 ISO published the initial release of STEP as international standards ( IS ) with the parts 1, 11, 21, 31, 41, 42, 43, 44, 46, 101, AP 201 and AP 203.

The publication of these new editions coincide with the release of the new ISO product SMRL, the STEP Module and Resource Library, in 2010 that contains all STEP resource parts and application modules on a single CD.

This makes STEP the biggest standard within ISO.

The AP 221 model is very similar to the ISO 15926-2 model, whereas AP 221 follows the STEP architecture and ISO 15926-2 has a different architecture.

The more recent " Product Data Exchange Specification " ( PDES ) project in the U. S., the related ISO Standard for the exchange of product model data ( STEP ) and the Computer Integrated Manufacture Open Systems Architecture ( CIMOSA ) project in the European Economic Community have whole heartedly accepted the notion that useful data sharing is not possible without formal semantic data models of the context the data describes.

ISO 10303-22 is a part of the implementation methods of STEP with the official title < u > S </ u > tandard < u > d </ u > ata < u > a </ u > ccess < u > i </ u > nterface or simply SDAI.

Today the term SDAI is sometimes used for all kinds of APIs supporting STEP, even if they only partially follow the strict functionality as defined in ISO 10303-22 and its implementation methods, or not at all.

* CAD, ISO 4217 currency code of the Canadian dollar

The PMI annotation is created on the 3D CAD model, associated to edges and faces, and can be exported into neutral formats such as Siemens JT and ISO 10303 STEP.

ISO 13567 is an international Computer-aided design ( CAD ) layer standard.

** Technical product documentation — Organization and naming of layers for CAD — Part 3: Application of ISO 13567-1 and ISO 13567-2

The ISO / IEC 8859 standard is designed for reliable information exchange, not typography ; the standard omits symbols needed for high-quality typography, such as optional ligatures, curly quotation marks, dashes, etc.

ISO 8601 Data elements and interchange formats – Information interchange – Representation of dates and times is an international standard covering the exchange of date and time-related data.

In many countries the ISO codes for the more common currencies are so well known publicly that exchange rates published in newspapers or posted in banks use only these to delineate the different currencies, instead of translated currency names or ambiguous currency symbols.

NFC standards cover communications protocols and data exchange formats, and are based on existing radio-frequency identification ( RFID ) standards including ISO / IEC 14443 and FeliCa.

* RSA-KEM *: RSA key exchange mechanism ( draft of ISO / IEC 18033-2 )

The identification of CRS could be a full description of properties defined in ISO 19111 ; only an identifier given by some registry ( such as EPSG ) is used in most cases, since only such identification is enough for most information exchange purposes.

* End System-to-Intermediate System ( ES-IS ), a routing exchange protocol for use in conjunction with the protocol for providing the CLNS ( ISO 9542 ).

* Intermediate System-to-Intermediate System ( IS-IS ), an intradomain routing exchange protocol used in both the OSI and Internet environments ( ISO 10589 and RFC 1142 ).

* ISO 8583 -- standard for systems that exchange electronic transactions made by cardholders

* ISO 13499 -- describes the exchange of multimedia vehicle safety test data

The Open Systems Interconnection ( OSI ) protocols are a family of information exchange standards developed jointly by the ISO and the ITU-T starting in 1977.

ISO 10303 is an ISO standard for the computer-interpretable representation and exchange of product manufacturing information.

* ISO 18876 IIDEAS-Integration of industrial data for exchange, access, and sharing

Today a few APs have ARM based exchange formats standardized outside of ISO TC184 / SC4:

Many current PC operating systems are able to read Joliet-formatted media, thus allowing exchange of files between those operating systems even if non-Roman characters are involved ( such as Arabic, Japanese or Cyrillic ), which was formerly not possible with plain ISO 9660-formatted media.

STEP-XML is a short term for ISO 10303-28, Industrial automation systems and integration — Product data representation and exchange — Part 28: Implementation methods: XML representations of EXPRESS schema and data

It is an alternative method to STEP-File for the exchange of data according to ISO 10303.

ISO / IEC 11179 claims that it is a standard for metadata-driven exchange of data in an heterogeneous environment, based on exact definitions of data.
