<li>Examples: |

<ol> |
|
| 391 |
<li>date + author e-mail + author-assigned name or ID<br />The date is first so that the ID column is sorted by date</li> |
|
| 392 |
<li>institution ID + institution-assigned name or ID</li> |
|
| 393 |
<li>web interface permalink</li> |
|
| 394 |
<li>database host + database name + <em>permanent</em> primary key</li> |

<ul> |
| 396 |
<li>Choose one ID to serve as the <em>preferred ID</em>. This becomes the database primary key.</li> |
|
| 397 |
<li>Choose the ID which is most directly associated with the identified object: |
|
| 398 |
<ol> |
|
| 399 |
<li>a domain identifier</li> |
|
| 400 |
<li>a permanent URL</li> |
|
| 401 |
<li>a <em>permanent</em> primary key</li> |
|
| 402 |
</ol> |
|
| 403 |
</li> |
|
| 404 |
<li><em>Within</em> these categories, choose the <em>shortest</em> string which is globally unique</li> |
|
| 407 |
<li>From multiple IDs, the <em>preferred ID</em> becomes the database primary key</li> |
|
| 408 |
<li>Use the ID which is most directly associated with the identified object</li> |
|
| 409 |
<li>The preferred ID should be <em>human-readable</em> whenever possible. A name or date should always be used in preference to a number.</li> |
|
| 410 |
<li>Choose the <em>shortest</em> string which satisfies the above criteria</li> |
