When creating HighWire (arthw.dtd) SGML, when using the element inter-ref there are a variety of currently supported codes that can be used in locator-type attribute to identify links to external databases. These are:

• gen -- NCBI's nucleotide database
• genpept -- NCBI's protein database
• pirdb -- Protein Information Resource
• mmdb -- NCBI's structure database (Molecular Modeling DataBase)
• omim -- NCBI's Online Mendelian Inheritance in Man
• ec -- Enzyme Collection
• sprot -- SwissProt (ExPASy Molecular Biology Server)
• pdb -- Protein Data Bank (formerly Brookhaven Data Bank)
• ncbigeo -- NCBI's GEO (Gene Expression Omnibus) database
• emblalign -- EMBL-ALIGN

   <inter-ref locator="A23187" locator-type="gen">A23187</inter-ref>

If the files cannot be tagged using inter-ref to identify database links, the HighWire parsing system (HPS) will make an attempt to resolve links to NCBI's nucleotide links on its own. It creates the links only if a certain pattern in the sentence is met.

HPS restricts itself to this specific type of pattern matching in order to avoid creating "false positive" links, which would frustrate the user. It will not attempt to create additional links to other databases, unless a publisher has requested broader attempts at linking. Generally, if additional links beyond NCBI's nucleotide are required, the vendor should then be using the appropriate inter-ref tagging for all database links (and if this is a new approach for a particular journal, then your content developer should be notified of the change).

If there is a new external database that you would like to have link support for, please contact your content developer with an outline of the suggested change and information on the database.
