ISA-95 is an abstract specification that has no data model. The B2MML implementation further refined the ISA-95 standard to include a set of standard data types. They selected the UN/CEFACT for this data type definition. These standard data type are now the default data type of ISA-95 Models In order to support transformation between the B2MML mapping and the OPC UA mapping of the ISA-95 Information models a mapping of UN/CEFACT is required.

The UN/CEFACT core component types are a common set of types that define specific terms with semantic meaning, such as the meaning of a quantity, currency, amount, identifier, and language. The UN/CEFACT core components were defined in a core components technical specification (CCTS) developed by the ebXML project now organized by UN/CEFACT and ISO TC 154. This definition also includes supplementary components which provide metadata that refine the value domain. See CCTS for additional information.

This standard defines a data representation model that is compatible with CCTS. The value of a content component is represented by the Value Attribute of a Variable, and the supplemental components that are defined in CCTS are represented as Properties of the DataType. In addition these supplemental Properties may optionally be defined for Variables.

Most of the CDTs, defined in CCTS, are defined as CDT DataTypes in this standard but some CDTs are mapped to OPC UA Built-in DataTypes directly.

All supplemental Properties defined as part of a CDT DataType include the definition of a default value. This allows a Server to not require the addition of the optional Properties, while still allowing a client to obtain the value for the CDT DataType supplemental Properties. However, for some DataTypes or VariableTypes the supplemental Properties may have different values on instances than the default value. For example, a Unit of Measure type depends upon measurement data. In this case, the Server shall duplicate the supplemental Property from the CDT DataType and to the Variable. A client shall try to read the supplemental Property from the Variable first, if the Property does not exist on the variable than the Client shall read the supplemental Property from the CDT DataType.

Figure 16 – Basic data representation model

Third parties may define VariableTypes that rely on CDT DataTypes to enhance data representation methodology. This approach will allow the use of generic clients that support performing actions based on a type system (programming against a type system). Figure 17 illustrates a type definition based on a CDT type. This is an enhanced feature but this standard recommends using the enhanced representation instead of the basic representation model.

Figure 17 - Enhanced data representation model

Figure 18 illustrates an example of the Amount and the Measure types defined in CCTS. In this example, a value of Currency Property is commonly used in UA Server but a value of Unit Property relates to a measurement value that is temperature.

CCTS defines a finite set of primitive data types that shall be used for a Content Component. These data types are mapped to OPC UA CC (Content Component) DataTypes which are OPC UA Built-in DataTypes or DataTypes defined in the following clauses. Table 10 defines mapping between the primitive data types for the Content Component and the CC DataTypes.

According to ISO 8601—2000, ‘calendar date representations are in the form [YYYY-MM-DD]. [YYYY] indicates a four-digit year, 0000 through 9999. [MM] indicates a two-digit month of the year, 01 through 12. [DD] indicates a two-digit day of that month, 01 through 31. For example, "the 5th of April 1981" may be represented as either "1981-04-05" in the extended format or "19810405" in the basic format.’

The standard also allows for calendar dates to be written with reduced precision. For example, one may write "1981-04" to mean "1981 April", and one may simply write "1981" to refer to that year or "19" to refer to the century from 1900 to 1999 inclusive.

Although the standard allows both the YYYY-MM-DD and YYYYMMDD formats for complete calendar date representations, if the day [DD] is omitted then only the YYYY-MM format is allowed. By disallowing dates of the form YYYYMM, the standard avoids confusion with the truncated representation YYMMDD (still often used).

This DataType defines a decimal value. The format of this value conforms to the following formula

For this release the OPC UA stacks and infrastructure does not support Decimal as a base type, thus this type must be mapped to a ByteString and the ByteString must be passed to the SDK and/or Stack. This DataType has to be handled by the application.

Decimal can be encoded in a number of ways and can be defined to have 32, 64 and 128 varieties. Since the OPC UA stacks do not natively support this encoding only a single Decimal type is being defined. This will allow the stacks in the future to be expanded to support Decimal32, Decimal64 and Decimal128. The encoding of decimal is also defined by more than one group using different encodings. The binary encoding being used for this release (and will always be used for the plain decimal binary string encoding) is a string that is 128 bit and follows the IEC TR 24732 definition for a decimal. It is summarised in the table below.

Subtype of the String defined in OPC 10000-3

According to ISO 8601—2000 ‘Durations are represented by the format P[n]Y[n]M[n]DT[n]H[n]M[n]S or P[n]W as shown to the right. In these representations, the [n] is replaced by the value for each of the date and time elements that follow the [n]. Leading zeros are not required, but the maximum number of digits for each element should be agreed to by the communicating parties. The capital letters P, Y, M, W, D, T, H, M, and S are designators for each of the date and time elements and are not replaced.

P is the duration designator (historically called "period") placed at the start of the duration representation.

Y is the year designator that follows the value for the number of years.

M is the month designator that follows the value for the number of months.

W is the week designator that follows the value for the number of weeks.

D is the day designator that follows the value for the number of days.

T is the time designator that precedes the time components of the representation.

H is the hour designator that follows the value for the number of hours.

M is the minute designator that follows the value for the number of minutes.

S is the second designator that follows the value for the number of seconds.

For example, "P3Y6M4DT12H30M5S" represents a duration of "three years, six months, four days, twelve hours, thirty minutes, and five seconds". Date and time elements including their designator may be omitted if their value is zero, and lower order elements may also be omitted for reduced precision. For example, "P23DT23H" and "P4Y" are both acceptable duration representations’

This DataType defines a value which is a normalized string. Some Unicode characters have multiple equivalent binary representations consisting of sets of combining and/or composite Unicode characters. The Unicode standard defines a process called normalization that returns one binary representation when given any of the equivalent binary representations of a character. The Win32 and the .NET Framework currently support normalization forms C, D, KC, and KD, as defined in Annex15. This definition of NormalizedString uses Normalization Form C for all content, because this form avoids potential interoperability problems arising from the use of canonically equivalent, yet different, character sequences in document formats

ISO 8601 uses the 24-hour clock system. The basic format is [hh][mm][ss] and the extended format is [hh]:[mm]:[ss].

[hh] refers to a zero-padded hour between 00 and 24 (where 24 is only used to notate midnight at the end of a calendar day).

[mm] refers to a zero-padded minute between 00 and 59.

[ss] refers to a zero-padded second between 00 and 60 (where 60 is only used to notate an added leap second).

So a time might appear as either "134730" in the basic format or "13:47:30" in the extended format.

It is also acceptable to omit lower order time elements for reduced accuracy: [hh]:[mm], [hh][mm] and [hh] are all used.

Midnight is a special case and can be referred to as both "00:00" and "24:00". The notation "00:00" is used at the beginning of a calendar day and is the more frequently used. At the end of a day use "24:00"

MIMEContentType defines the Multipurpose Internet Mail Extensions (MIME) media type of the binary object. This standard recommends use of text code defined in IETF RFC2045, IETF RFC2046 and IETF RFC2047 for the MIME. In this case the MIMEContentType is actually referencing the Content-Type that is defined as part of the MIME type and commonly used as a reference to a specific MIME. The top-level media type is used to declare the general type of data, while the subtype specifies a specific format for that type of data. Thus, a media type of "image/xyz" is enough to tell a user agent that the data is an image, even if the user agent has no knowledge of the specific image format "xyz". Such information can be used, for example, to decide whether or not to show a user the raw data from an unrecognized subtype such an action might be reasonable for unrecognized subtypes of "text", but not for unrecognized subtypes of "image" or "audio".

CharacterSet defines a specific character set of text data if MIME is text. This standard recommends use of text code defined in IANA for the CharacterSet.

Encoding defines an encoding/decoding mechanism of the Binary Object. If contents of the Binary Object are encoded in specific formats, UA Server represents the formats using this supplemental to indicate a code to identify the encoding. Generally, UA Server doesn’t need to encode Binary Objects since the UA Stack always Encodes Messages in the appropriate format defined in OPC 10000-6. This standard recommends the use of text codes defined in IETF RFC2045, IETF RFC2046 and IETF RFC2047 for the Encoding.

MIMEListId represents the identification of a list of codes (refers to the MIMEContentType).
