TECHNICAL OUTLOOK standards bodies in some cases providing an additional level of modification for local conditions. CrossRef has engaged in discussions with a group of standards publishers and has made changes in the deposit schema to represent the relationships among these multiple components in a way that meets the needs of the standards world. Increasingly, CrossRef members are interested in making deposits for a range of non-traditional content types — online training materials, learning modules, and more — loosely classified as online resources. CrossRef accepts deposits for non-traditional items such as reports, papers, and databases (covering a variety of content), but to accommodate these newer items effectively will call for a dedicated approach to defining their metadata. CrossRef staff members plan to engage with interested parties to establish requirements through a dialog that is expected to be ongoing as additional types of online resources arise. Work is under way on enabling members to include information in their deposits that represents relationships of items to others in the CrossRef database as well as to items with non-CrossRef-assigned DOIs, so that, for example, the metadata for a review article can indicate the work being reviewed and the metadata for a research article can indicate its cited data sets. The need for this capability has to an extent been highlighted by the uptake of CrossMark. Established with a relational mechanism for displaying updates and corrections to articles and their funding sources, the service is also being used by publishers as a reservoir for other kinds of entries, such as links to comments in blog posts. The new capability will provide publishers with a direct path for embedding all types of relationships in their metadata deposits, opening the way for them to build new tools on their web sites by which readers can track these connections. The CrossRef branding initiative has underscored the importance of communicating the interrelatedness of CrossRef’s activities, and it is worth noting that the work on standards, online resources and representing relationships among content items all ties in to CrossRef’s core function of gathering and redistributing metadata in ways that serve the needs of an ever-expanding group of stakeholders.
