Authority files are used to uniquely identify entities such as resources, persons, families and corporate bodies, as well as their properties, such as relations and features. Originally created in the analog world, their existance is crucial for providing adequate information retrieval and analysis in the digital age. Computers, even more than humans, are poor at handling ambiguity. Therefore each entity and each step have to be thoroughly and precisely defined. By assigning the same identifier, computers are told which terms, names or numbers refer to the same entity or have the same meaning and when carrying out a query they are able to navigate from identifier to identifier and to collect, aggregate and organise the retrieved information. We are heading towards the release of massive data collections like library catalogues or research datasets to be directly accessible over the Internet. This is the crucial improvement that we are expecting from the adoption of the so called open linked data, a strong push towards the transformation of the Web of documents into the Web of data. Given these circumstances, experts are claiming that controlling permanent and unique identifiers is within the authority work more crucial than organising and validating strings. In many cases the identifier is used to identify a cluster of identifiers. This clustering mechanism can facilitate the creation of systems made of data differing in structure, language and format, as those brought together in portals. Identifiers can be part of a strategy aiming at preserving the original context of the record, as well as enhancing what is known as cross-fertilisation and the creation of new dynamic e-reference tools. |
