- Secure active Project Spaces in which groups work, during their research projects, building collections of data files, annotations, and metadata (through a web interface or via researcher's software writing directly to their project space via the SEAD API),
- Publishing Services that cache, analyze, and manage the submission of publication requests from researchers to repositories partnering with SEAD. These services use information about repositories and their policies (submitted by the repository), about people and their affiliations (harvested from sources such as ORCID), and the contents of publication requests (submitted by researchers from their project spaces or third-party infrastructure), to 'match' requests with compatible repositories on the basis of a configurable set of rules that may involve limits on total size, maximum file size, file types, affiliations of authors, and other metadata and statistics. In SEAD's 2.0 version, researchers can review the results of this assessment and decide whether to adjust their publication requests (adding required metadata, removing unacceptable files, etc.) and to then submit to a repository of their choice. SEAD's publishing services then make such requests available for repositories to discover and retrieve, and then tracks the status of the repository's processing of a request through to the final completion and assignment of a persistent identifier (e.g. DOI).
- Repositories partnering with SEAD to acquire and preserve data publications that meet their institutional interests. Repositories may range from institutional repositories with rich services (e.g. based on DSpace or Fedora4) to repositories with fewer features but lower costs and/or higher scalability. SEAD provides a RESTful API (see the SEAD 2.0 Publication API Walkthrough:) that repositories can use to interact with SEAD and retrieve data publication requests. Repositories working with SEAD had demonstrated connections via this API to institutional repositories. SEAD has also worked to develop software tha can efficiently and scalably package data publication for storage and retrieval of publications on large file systems and cloud storage. All of this software is avialable for use and/or extension and modification by respositories interested in connecting to SEAD.
The SEAD Reference Publisher
The SEAD Reference Publisher is a lightweight web application that can publish and provide access to data publications originating in SEAD. It consists of two interacting components that manage 1) The SEAD publication process from retrieval of a request from SEAD's publishing services to packaging, storage, and submission of a persistent identifier back to SEAD, and 2) providing access to the stored data through a landing page associated with the persistent identifier minted for the data. The reference publisher serves several purposes:
