One of the following predefined conformance profiles may be chosen: full p
14、rofile, fidU PKS profile, and foundation profile. For a definition of these profiles refer to clause 6. Additional application profiles are subject to registration as defined in 6.2. While application-profile constraints the conformance-profile by “linguistic” means, assuming that specific name is k
15、nown to the IIF Gateway, or to the application, the same is achieved by profile-definition, pointing to the formal definition how data types shall be used in the current IIF data stream, or simply, giving a “generic example” of what is allowed inside the conformance-profile. The profile-definition c

Both application-profile and profile-definition may constrain the range implied by conformance-profile, but never extend it.

19、No. 005 ContentsHeader Semantics The ContentsHeuder entity provides some common information about the contents of the IIF data stream. No further semantics are defined for the convention of the title, owner, date-and-time, and message components. Also, no semantics are defined for the application-da
20、ta component which can be represented using any ASN.1 tY Pe. The externaLreferences component describes the sources of data which are outside of the current IIF data stream. The access-information component provides additional information which will facilitate random access to the content of the cur
21、rent IIF data stream. It points to the specification of an external file in the list of external references. The type-guide component is a pointer to an external data repository from which the default attributes are inherited and from which type definitions can be referenced. NOTE - Information fiel
22、ds, such as “processing platform” or “acquisition process” are regarded as too application- specific to be included in this header as a separate entity. This kind of information can either be put into the message field as readable text or handled as an image annotation or image attribute (using eith
23、er one of the built-in fields or a freeform field). EXAMPLE - The application-data component (as well as any other component that is typed with the ASN. 1 type ANY) could be structured by an application in the following way: ApplicationData . -= SET OF . .

29、EC 12087- 1. - the contents-element provides a recursion because its subentities refer back to the ContentsBody entity. According to the constraint given below, this recursion is prohibited. The only reason for incorporating the contents-element component into the syntax is to prepare the introducti
30、on of a hierarchical type definition and validity space concept that may be given in a separate Ammendment to this International Standard. Image annotations and image-related data are provided in two ways: bound to images, using the corresponding subentities within the Image entity, or separate from
31、 images using the ContentsBody entity as stated above. The latter way allows for the exchange of non-iconic parameters from and to the IPI-PIKS without any image data.

NOTES 1 The following fields of the “representation attribute”, defined in ISO/IEC 120874, are represented in the IIF-DF by the ImageStr
34、ucture entity and its subentities: image size, barId data type, image structure code. 2 This entity and its subentities do not contain pixel values.

38、ax entity No. 211 ExternalReference and IIF syntax entity No. 212 ExternalAddress Semantics The ExternalReference entity supports a referral mechanism to an externally stored data set within a heterogeneous and distributed computing environment. NOTE - Within ISO/IEC 12087, this mechanism is exclusi
39、vely used to refer to a field of pixel values that is not present within the current data stream. The object-address entity is used to describe the address of the external object. Both local environments (e.g., file names in a UNIX file system) and heterogeneous, distributed environments (e.g., addr
40、esses of objects that may be obtained via ftp) are supported. The object-format component allows for a description of the format of the externally stored data set. This is done by a unique identifier of the grammar. If this component is absent, the external data portion shall be interpreted as a Ref
41、erencedUnit entity, according to the IIF-DF syntax. The object-internal-id component is an optional component which may be used to identify a specific object part within the object specified by the object-address component (e.g., by giving a byte offset that points from the top of the file to the be
42、ginning of the valid data). A concrete interpretation of this component may be specified within an application profile. Application profiles are subject to registration, as defined in 6.2. The entity-address component is an optional component which allows to constrain the refernced data to either a
43、specific segment and its nested segments if the referenced data is an IIF data stream, or to an application specific information quanta if referenced data set is structured otherwise. The ExternaZAddress entity provides two alternatives for the representation of an external object address. The struc
44、tured-address component provides a unique location and name of the external object, according to ISO/IEC 1003 1, Distributed Office Application Model (DOAM), Part 2: Distinguished Object Reference (DOR). The cLeartext-address component may be used for an informal representation. A concrete interpret
45、ation of this component may be specified within an application profile. Application profiles are subject to registration, as defined in 6.2.

47、ax entity No. 301 ImageRelatedData Semantics The ImageRelatedData entity stands for the description of image-related data, as defined in ISO/IEC 12087- 1. The following types of image-related data are provided: match point, look-up table, histogram, region of interest, neighbourhood, and feature lis
48、t. The identifier component is used to associate the image-related data with those parts of an image structure which have the same identifier. The usage component allows for a verbal description of the way the image-related data type is used. The types of image-related data named above are given by
49、the histogram, look-up-table, region-of-interest, neighbourhood-array, static array, feature-list, value-bounds-collection, matrix, pixel-record, tuple, and referenced-data components. Instead of explicitly specifying one of these types, the ImageRelatedData entity may also reference the desired type (via an image-related data reference) from the name space of the current segment or from the name space provided by an external address. The data-required component is usable in the specification of
