I recently introduced a simple visualization of data from the CrossRef Participation Reports that provides quantitative insight into how completeness of CrossRef metadata collections with respect to eleven key metadata elements has changed between the backfile and the current record collections.

I recently introduced a simple metric for measuring metadata collection completeness with respect to elements in the CrossRef Participation Reports. The suggestion of this metric immediately led to speculation about relationships between collection size and completeness. Small collections include fewer records – are they more likely to be complete? Publishers with large collections have more resources – do they have more complete metadata?

All scientific communities have been linking research together for many years using references to related work in articles. Recently these communities are exploring options for linking to datasets and software. As part of this effort, the CodeMeta Project recently proposed a vocabulary for metadata for code based on schema.org.

Over the last several years CrossRef has grown into one of the largest and most significant metadata repositories in the world. It contains over 100,000,000 registered content items and offers many services to help members and other users take advantage of that content. In addition to managing registered content, CrossRef makes links between resources. It is the connective tissue for the web of scholarly communications.

California Digital Library (CDL) and Dryad recently announced a partnership to address researcher needs and to “move the needle” on digital data adoption throughout the scholarly research community by working together to understand and respond to researcher needs for high-quality scientific data publishing infrastructures.

High-quality metadata can help users discover data and other resources in many ways. Good titles, abstracts, and keywords, along with spatial and temporal extents, go a long way with many search strategies. Adding schema.org metadata to landing pages can also help. A second discovery strategy, more like browsing, comes into play once someone finds something interesting.

The Doe family consists of mother Jane and her son John. Identifying people and relationships is an important function of metadata. The ISO TC211 metadata standards provide a comprehensive framework for many important metadata use cases. Could ISO metadata be used to describe the Doe family? ISO metadata describes objects with types and properties.

The idea that the language we use to talk about things shapes the way we think or can think about those things has been around since the 1800’s and even has a name, the Sapir–Whorf hypothesis, proposed during 1954.

Many datasets and products are documented using approaches and tools developed by data collectors to support their analysis and understanding. This documentation exists in notebooks, scientific papers, web pages, user guides, word processing documents, spreadsheets, data dictionaries, PDF’s, databases, custom binary and ASCII formats, and almost any other conceivable form, each with associated storage and preservation strategies.
