Common questions
FAQ
Can both Pure and Symplectic Elements support a REF submission?+
Yes — both are used by UK institutions to gather, manage, and prepare Research Excellence Framework submissions, including assembling outputs, impact, and environment data. The choice between them for REF purposes is usually driven by institutional preference and existing workflows rather than a difference in REF capability.
Is either of them open source?+
No — both Pure and Symplectic Elements are proprietary commercial products, Pure from Elsevier and Symplectic Elements from Digital Science. Institutions seeking an open-source CRIS would look elsewhere, for example to DSpace-CRIS.
How do they differ in gathering publication data?+
Both harvest publication and research data from external sources to build researcher profiles, but they emphasise different workflows — for instance, the balance between automated population and researcher-led claiming and verification of records. The practical difference an institution experiences depends heavily on local configuration.
