| - | 1030 | The following rules are followed by the OID repository administrator to validate OID descriptions: |
|
| - | 1031 | <ul> |
|
| - | 1032 | <li>The description shall be as short as possible (usually, not more than one line) and focus on <em>what</em> (i.e., which object) is identified by the OID. The description shall not be a sentence (with a verb). Consequently, the description does not end up with a full stop "." (except when the full stop is part of an abbreviation). See also the <a href="#syntax-rules">syntax rules</a>.</li> |
|
| - | 1033 | <li>The description should be easily understandable by any user of the OID repository. Substantives should not be put one after the other without inserting small words like "for", "of", etc. This helps understanding the description and avoids ambiguities when translating to other languages.</li> |
|
| - | 1034 | <li>Useless expressions like "OID for", "OID identifying", "Root OID for", "Top arc for", "Arc for", "This OID describes", "This arc describes", etc., are forbidden.</li> |
|
| - | 1035 | <li>Words are not capitalized (contrarily to what is usually done for paper or book titles in English) except for an abbreviation or acronym which is put between parentheses after the expression that defines it (with each letter of the abbreviation being capitalized in its definition), e.g., Meaning of My Abbreviation (MMA).</li> |
|
| - | 1036 | <li>Any text (e.g., how it is used, how child OIDs are allocated, etc.) which is not related to <em>what</em> is identified by the OID shall be moved to the "Information" part. Any text which can be assimilated to a publicity or a company description shall be avoided (a URL can be associated to the company name).</li> |
