All three components of the TYPO3 Beaconizer can be used independently from each other. There is no obligation to harvest links from BEACON files. You can use the SeeAlso plugin in standalone mode together with the webservice at beacon.findbuch.de. The BEACON generator can also be used standalone. Everything really depends on your use case and your data.
Only two things are needed:
- Your data (pages, records in an extbase extensions etc.) should use identifiers from an authority file (GND, VIAF etc.)
- You need to create some BEACON provider records which point to the BEACON files you wish to use
Please read the following sections of the manual on how to do that.
