Short answer
Historical Digitised historical or newly generated maps can be linked to existing data or repositories when they are described with adequate metadata and connected through persistent identifiers, standard formats, or references to related datasets and digital collections.
Detailed answer
Yes. New historical maps can be linked to existing data or repositories if they are prepared in a way that supports discovery, reuse, and interoperability. In practice, this means the map should have clear metadata, such as title, creator, date, geographic coverage, scale, source, and rights information. It should also include information that connects it to related resources, such as specimen records, collection objects, field observations, archival documents, or other map series.
A strong way to support linking is to use persistent identifiers, such as DOIs or stable repository identifiers, for the map itself and for related datasets or metadata records. These identifiers make it easier to connect resources across systems and keep links stable over time.
It is also helpful to use common metadata standards and controlled vocabularies where possible. That makes the map easier to integrate into interoperable repositories and discovery platforms. If the map has been georeferenced, the process should be documented as well, because spatial coordinates can improve linking with other geospatial or collection-based data.
In short, the map does not need to stand alone. If it is documented properly and deposited in a repository that supports interoperable metadata and stable identifiers, it can become part of a wider network of related digital resources. This approach is relevant not only for historical maps but also for maps representing current or near real-time data.
