secondaryAccession (AC line) lists the secondary accession numbers associated with This entry. Description (DE line) contains general descriptive information about the sequence stored KeyWord (KW line) provides information which can be used to generate cross-reference indexes of the sequence entries based on functional, structural, or other categories deemed important reference comprise the literature citations and data submissions within the database dbreference (DR line) cross-references other databases which contain information related to other entry comment (CC lines) are free text comments about the entry, and may be used to convey any sort of information thought to be useful that is unsuitable for inclusion in other elements. Feature (FT lines) provide a mechanism for the annotation of the sequence data. contains information of the feature source nameset (OS line) specifies the preferred scientific name of the organism which was the source of the stored sequence lineage (OC line) contains the taxonomic classification of the source organism. Note : lineage should be part of the taxonomy database. Therefor lineage shouldn't appear in the flat file qualifier provide a general mechanism for supplying information about features RP line RC line can contains the information of an electronic (or online) article. Stores all information of the reference block in EMBL (RN, RP, RC, RA, RT and RL line). citation comprise the literature citations within the database The citation type stores all information about a citation. The equivalent information in the flatfile can be found in the RA (authors), RT (title), RX (PubMed/MEDLINE IDs) and RL (citation location information such journal name, volume numbers, pages, etc.) lines. dbreference cross-references other databases which contain information related to other entry consortium (RG line: Reference Group) lists the working groups/consortia that produced the record title ( RT line) gives the title of the paper (or other work) editor of a book. Stored in the RL line in the flatfile format. Only valid for books. Example: RL (In) Magnusson S., Ottesen M., Foltmann B., Dano K., RL Neurath H. (eds.); RL Regulatory proteolytic enzymes and their inhibitors, pp.163-172, RL Pergamon Press, New York (1978). The authors of the citation. Stored in the RA line in the flatfile format, except for citing citation where it is stored in the RL line. Example (standard citation): RA Galinier A., Bleicher F., Negre D., Perriere G., Duclos B., RA Cozzone A.J., Cortay J.-C.; Example (citing citation): RL Unpublished results, cited by: RL Shelnutt J.A., Rousseau D.L., Dethmers J.K., Margoliash E.; RL Biochemistry 20:6485-6497(1981). patentApplicant (RL line) lists the patent applicants, normally company names. locator (RL line) contains the conventional citation information for : - data submissions Example RL Submitted (19-NOV-1990) to the EMBL/GenBank/DDBJ databases.

Used by type: thesis. Database cross-references, equivalent to the flatfile format's DR line.
