Metadata, Metadata, Metadata

February 26, 2019 | By | No Comments

My project entails the creation of a digital library for the management and public outreach of archaeological cultural heritage. The initial work towards this goal has entailed the building a metadata scheme. That is, finding the right data to describe data. There are a number of factors that go into describing data, but the most important and obvious goal should be its usefulness. There are three things I have done so far that I think have helped to make my metadata scheme useful:

  1. Researching established metadata schemes
  2. Utilizing metadata schemes already in use for the collections.
  3. Learning the collections management system, KORA, to better build my metadata scheme.

Established metadata schemes already exist to describe resources. Utilizing one or more of these uniform systems to describe data has many benefits. First, it makes it easier to compare and search through different collections from different organizations if the entities for describing those collections are the same. Secondly, it does some of the work for you by providing a useful list of possible terms to use that you may not have thought of. The Dublin Core Metadata Initiative, for example, provides standard metadata entities and their definitions for describing resources. These include 15 “core properties” such as contributor, coverage, creator, date, description, identifier, etc. These entities are included in my metadata scheme, especially for the description of documentary resources like articles, newspaper clippings, and journals.

Using established, international metadata schemes is an important way to clearly organize and describe your data in a way that can be compared and clearly understood. But it is also important to transfer data that is already in the books. These collections are already being managed, and as such, have established metadata describing these collections. Transferring data already on record into the digital library will be much easier if the entities from both systems are somewhat analogous. To that end, I am using entities from collections management software already being utilized on campus to influence my choice of entities and the organization of the metadata scheme. ARGUS is one such software system.

The organization of the metadata scheme is also being heavily influenced by KORA; the collections management software program I am utilizing to build the digital library. The structure of KORA is organized around projects, forms, pages, fields and records.  The project will likely contain many forms which will be equivalent to the individual collections within the digital library. The metadata scheme will then be put into pages which will contain fields where data can be entered. The pages and fields will be the metadata scheme. A record will be the actual data describing an object that has been entered into the metadata scheme. The goal for my next blog post is to better describe the actual organization of my metadata scheme after putting it into KORA.
