| # Database Harvesting {#database_harvester} | ||
|
|
||
| This harvesting type uses a database connection to harvest metadata stored in a database table. | ||
|
|
||
| ## Adding a Database harvester | ||
|
|
||
| To create a Database harvester go to `Admin console` > `Harvesting` and select `Harvest from` > `Database`: | ||
|
|
||
|  | ||
|
|
||
| Providing the following information: | ||
|
|
||
| - **Identification** | ||
| - *Node name and logo*: A unique name for the harvester and optionally a logo to assign to the harvester. | ||
| - *Group*: Group which owns the harvested records. Only the catalog administrator or users with the profile `UserAdmin` of this group can manage the harvester. | ||
| - *User*: User who owns the harvested records. | ||
|
|
||
| - **Schedule**: Scheduling options to execute the harvester. If disabled, the harvester should be executed manually from the harvesters page. If enabled a schedule expression using cron syntax should be configured ([See examples](https://www.quartz-scheduler.org/documentation/quartz-2.1.7/tutorials/crontrigger)). | ||
|
|
||
| - **Configure connection to Database** | ||
| - *Server*: The database server IP/Hostname. | ||
| - *Port*: The database port. For example, for Postgres usually 5432. | ||
| - *Database name*: The database name to connect. | ||
| - *Table name*: Table name with the metadata. The name must begin with a letter (a-z) or underscore (_). Subsequent characters in a name can be letters, digits (0-9), or underscores. | ||
| - *Metadata field name*: Table field name that contains the metadata. The name must begin with a letter (a-z) or underscore (_). Subsequent characters in a name can be letters, digits (0-9), or underscores. | ||
| - *Database type*: Database type. Currently supported Postgres and Oracle. | ||
| - *Remote authentication*: Credentials to connect to the database. | ||
|
|
||
| - **Search filter**: allows to define a simple field condition to filter the results. | ||
| - *Filter field*: Table field name used to filter the results. The name must begin with a letter (a-z) or underscore (_). Subsequent characters in a name can be letters, digits (0-9), or underscores. | ||
| - *Filter value*: Value to filter the results. It can contain wildcards (%). | ||
|
|
||
| - **Configure response processing for database** | ||
| - *Action on UUID collision*: When a harvester finds the same uuid on a record collected by another method (another harvester, importer, dashboard editor,...), should this record be skipped (default), overriden or generate a new UUID? | ||
| - *Validate records before import*: If checked, the metadata will be validated after retrieval. If the validation does not pass, the metadata will be skipped. | ||
| - *XSL filter name to apply*: (Optional) The XSL filter is applied to each metadata record. The filter is a process which depends on the metadata schema (see the `process` folder of the metadata schemas). | ||
|
|
||
| It could be composed of parameter which will be sent to XSL transformation using the following syntax: `anonymizer?protocol=MYLOCALNETWORK:FILEPATH&[email protected]&thesaurus=MYORGONLYTHEASURUS` | ||
|
|
||
| - *Batch edits*: (Optional) Allows to update harvested records, using XPATH syntax. It can be used to add, replace or delete element. | ||
| - *Translate metadata content*: (Optional) Allows to translate metadata elements. It requires a translation service provider configured in the System settings. | ||
|
|
||
| - **Privileges** - Assign privileges to harvested metadata. |
