Using the Registry |

------------------ |
| 34 | 34 |
Metacat's optional Registry provides a simple Web-based interface for creating, |
| 35 |
editing, and submitting metadata to the Metacat repository (Figure 4.1). The

editing, and submitting metadata to the Metacat repository (screenshot below). The
|
|
| 36 | 36 |
interface includes help documentation, and can be customized using Metacat's |
| 37 | 37 |
configuration settings. The Registry also includes an administrative interface |
| 38 | 38 |
for managing LDAP user accounts, which is useful if you are using LDAP as your |

Archive a document and move the pointer in xml_documents to xml_revisions, |

effectively "deleting" the document from public view, but preserving the |

revision for the revision history. No further updates will be allowed for |
|
| 499 |
the Metacat document that was "deleted". All revisions of this identifier are no longer |

public. |

.. warning:: |
|
| 503 |
It is not possible to "delete" one revision without "deleting" all |
|

revisions of a given identifier. |

The following is an example of a Web form (see figure) that can perform all |

When Metacat receives a query via HTTP (screenshot below), the server creates a
|
|
| 552 | 558 |
"pathquery" document, which is an XML document populated with the specified |
| 553 |
search criteria (Figure 4.10). The pathquery document is then translated into
|
|
| 554 |
SQL statements that are executed against the data base. Results are translated
|
|
| 559 |
search criteria. The pathquery document is then translated into |
|
| 560 |
SQL statements that are executed against the database. Results are translated |
|
| 555 | 561 |
into an XML "resultset" document, which can be returned as XML or transformed |
| 556 | 562 |
into HTML and returned (specify which you would prefer with the returnfield |
| 557 | 563 |
parameter). You can also opt to submit a pathquery document directly, |
