Commonalities and differences in the curation workflow stages

Curation stage	Commonalities	Differences
Source collection	PubMed search (abstracts) Full-text articles (pdf)	Number of papers to be curated Acceptance of sources outside of PubMed (e.g. author submission)
Paper selection (triage)	Manual process by humans Primarily based on abstract Assignment of curation priorities Identification of genes/proteins	Database-specific selection criteria (e.g. species, gene/function, novelty) Identification of additional bio-entities (e.g. anatomy, cell type)
Full curation	Gene (function) centric Use of full text Use of controlled vocabularies and ontologies Identification of experimental evidence Contacting authors when needed	Annotating database/species-specific entities and relationships Annotating images (Xenbase)
