We cannot allow arbitrary schema definitions.<\/h2>\n

ISO DP2 requires a framework for use by prospective qualified people so that experts can verify that future developments and\/or extensions are conformant with the provisions provided in the standard.
\nThere is no international standard that has not defined a framework. The data elements and usage may change by jurisdictions and auditors but how to specify requirements on data items shall be provided as a framework.The development of an audit data service standard requires an audit data service semantic model framework. We cannot allow arbitrary schema definitions. It is essential to have a framework on which to determine whether the defined schema is compliant with our standards. <\/p>\n

DP2 and framework<\/h2>\n

ISO DP2 requires the following;<\/p>\n

\nThe objective of documents is to specify clear and unambiguous provisions in order to help international trade and communication.
\nTo achieve this objective, documents shall:
\n\u2022 be complete within the limits specified by their scope;
\nNOTE 1 When a document provides requirements or recommendations, these are either written explicitly, or made by reference to other documents (see Clause 10).
\n\u2022 be consistent, clear and accurate;
\n\u2022 be written using all available knowledge about the state of the art;
\n\u2022 take into account the current market conditions;
\nNOTE 2 There is sometimes a tension between what is technically feasible and what the market actually requires and is prepared to pay for.
\n\u2022 provide a framework for future technological development; <\/strong>
\n\u2022 be comprehensible to qualified people who have not participated in their preparation; and
\n\u2022 conform to the ISO\/IEC Directives, Part 2. A document does not in itself impose any obligation upon anyone to follow it. However, an obligation can be imposed, for example, by legislation or by a contract which makes reference to the document. A document shall not include contractual requirements (e.g. concerning claims, guarantees, covering of expenses), or legal or statutory requirements.

ISO Standards for data modeling and business document<\/h2>\n

Some of the important ISO standards for data modeling are introduced in the following my post.
\nISO Standards for data modeling and business document<\/a><\/p>\n

How is the framework defined in ISO?<\/h2>\n

ISO provide a framework for future technological development
\nExample: ISO 68-1 ISO general purpose screw threads \u2014 Basic profile \u2014 <\/a>
\nISO is not a collection of drawings of this kind, nor parts catalog.
\nISO does provide a framework for creating screw threads.<\/p>\n

\n\"\"<\/a><\/div>\n

As per ISO 68-1, basic profile is The theoretical profile of a screw thread in an axial plane
\ndefined by theoretical dimensions and angles common to internal and external threads.<\/p>\n

Figure 1<\/h4>\n
\n\"\"<\/a><\/div>\n

Above figure shows the basic profile for ISO general purpose metric screw threads (M). The
\nbasic profile for ISO general purpose metric screw threads is specified in ISO 68-1, \u201cISO
\ngeneral purpose screw threads – Basic profile – Part 1: Metric screw threads\u201d.<\/p>\n

\n\"\"<\/a><\/div>\n
\n\"\"<\/a><\/div>\n

Dimensions<\/h3>\n

The fundamental deviations and tolerances specified in ISO 965-1 are applied to the dimensions of the basic profile shown in figure 1 and derived from table 1.<\/p>\n
