| 17 | * <br/> |
|
| 18 | * {@link Guid} is an optional sub-element of {@link ItemEntry}.<br/> |
|
| 19 | * guid stands for globally unique identifier. It's a string that uniquely identifies the item. When present, an aggregator may choose to use this string to determine if an item is new. |
|
| 20 | * <guid>http://some.server.com/weblogItem3207</guid> |
|
| 21 | * <p/> |
|
| 22 | * There are no rules for the syntax of a guid. Aggregators must view them as a string. It's up to the source of the feed to establish the uniqueness of the string. |
|
| 23 | * <p/> |
|
| 24 | * If the guid element has an attribute named "isPermaLink" with a value of true, |
|
| 25 | * the reader may assume that it is a permalink to the item, that is, |
|
| 26 | * a url that can be opened in a Web browser, that points to the full item described by the |
|
| 27 | * {@link ItemEntry} element. |
|
| 28 | * <br/> |
|
| 29 | * An example: |
|
| 30 | * <guid isPermaLink="true">http://inessential.com/2002/09/01.php#a2</guid> |
|
| 31 | * <p/> |
|
| 32 | * isPermaLink is optional, its default value is true. If its value is false, the guid may not be assumed to be a url, or a url to anything in particular. |
|
| 33 | * <p/> |
|
| 34 | * |
|
| 35 | * Atom 1.0 description: |
|
| 36 | * <br/> |
|
| 37 | * The "atom:id" element conveys a permanent, universally unique identifier for an entry or feed. |
