Discover how OLIB uses the electronic location and access tag for import and export of Objects in OLIB.
|Indicators||0-4/7, 0-2/8||The indicators determine the method through which the resource is accessed and the relationship to the resource. Normally this is 4 (for http) and blank.
The second indicator maps directly to the Relation to Resource field on the Objects' Related Items and Control Data sheet.
If this is '0' or '1' (for "Resource" or "Version of resource" respectively) during import, then "Available Online" is set to "Yes" on the title record.
|Subfields||856: u, s, y, z||These Tags and the u, s and y subfields are exported by default. From Service Pack 10, the entire tag can be omitted by specifying that the Object itself should be excluded from the MARC export either at the Object level or at the Object Type level.|
|Imports to||All 4 of the above subfields are imported by default to an Object linked to the Title record.|
|Exports from||Data for these tags are extracted from the Objects linked to the Title during export. See below for a breakdown of this information. Objects whose content is within the OLIB database are not exported.
Objects can be excluded from the export individually or with a setting on their Object Type. The setting on the Object will take precedence over the setting on its Object Type

Example value - 856:
'4 $uhttp://worldcat.org/oclc/85364021$yView in WorldCat'
|u||http://worldcat.org/oclc/85364021||Uniform Resource Identifier - This is retrieved from the locator field on the Object record either directly or via mappings configured in the File to URL Mappings domain.
It is imported to the Objects' locator field as is.
|y||View in WorldCat||Link Text - This is exported from and imported to the Objects' Title field.|
|s||1234||File Size - This is retrieved from or imported to the Objects' size field (if set).
Whilst the export will simply export the numeric value (in bytes) without any grouping for human readability, the import will handle "KB", "MB" and "GB" in the incoming value, multiplying the number accordingly to represent the number of bytes.
|z||See other libraries that have this book||Public Note - This is imported into the Notes field on the Objects record.|
