4 Basic concepts on documents and documentation
4.1 General
Documents provide information necessary for different activities and purposes during the life cycle of a plant, system or equipment. The term documenr is not restricted to a paper-based presentation of the information. It also includes other forms of information storage. such as data files on electronic media or in a data base.
Information requires an agreed form of presentation to be understandable for a human reader. In most cases, such a form is defined only for traditional paper-based documents or similar ways of presentation In this standard, descriptions of document kinds are referring to the paper-based presentation. Other forms of visualisation, for example presentation on a video screen, are assumed to be equal or at least similar to the paper-based presentation.
In the context of this standard, it is necessary to distinguish between the following concepts and their interrelationship (see Figure 1):
4.2 Document kinds
A document kind shall be defined by
• a generic description of the characteristic type of information that a document prepared on the basis of this document kind is intended to contain; and
• its form of presentation.
Two different documents are of the same kind if they have similar characteristics concerning the content of information and the same form of presentation.
A document kind should neither be defined with respect to a described object nor to its intended purpose.
Each document kind is assigned a document kind class, see Clause 5.
4.3 Documents
A document:
• may provide specific information on an object of interest and may refer to that object:
NOTE 1 Documents can exist for which no clear object relationship is to be identified.
• may be classified by the relevant document kind class;
• may refer to its purpose (for what activity it is needed):
• may be visualized in an agreed form of presentation.
NOTE 2 A document can consist of one or more document pages.
4.4 Composite documents
A composite document has different parts of information content, each part being normally related to a different document kind class. For example, a document presenting an arrangement drawing together with a parts list is considered a composite document.
Special rules are required to assign a document kind class to a composite document, see 5.3.
4.5 Document sets
A document set is a collection of different documents, i.e. documents and composite documents, which is intended to be treated as a unit. A document set is not assigned a common classification.
NOTE II a document set requires a common classification, it basically becomes a composite document.
4.6 Documentation
A documentation is a collection of different documents, composite documents arid document sets related to a given subject. The constituents of a documentation are classified individually. The documentation as a whole is not assigned a common classification.
5 Classification of documents
5.1 Classification principles
The classification of documents shall be based on their characteristic content of information.
NOTE Documents are characterized by document kinds which are classified In the same way as documents
If a document can be characterized in different ways, the leading content of information shall govern its classification.
Documents shall be classified at least in two levels (Class-levels A2 and A3). They may additionally be classified in a preceding level (Class-level Al), see Figure 2.BS EN 61355-1-2008 pdf download.
