Mar 1996 - Oct 1997, National Center for Biotechnology Information
Participated in the development of the first version of PubMed system. Designed and developed the part of the system, which acquires data from publishers and uploads it into the database. It reads and processes the vendor supplied SGML files encoded using Document Type Definitions (DTD), extracts and validates the NLM specified fields, and converts the extracted fields into formats required by the MedLine and PubMed databases including ASN.1. This system is presently in production. It uploads large numbers of new articles from the leading scientific journals. This part of the system was designed with the Booch approach and implemented in C++, using Sun C++ compiler, RCS and CVS Version Control Systems, SGML, Perl 4, Bourne Shell, and Sybase Open Client CT-Library. Using UNIX crontab utility and Bourne shell scripts the developed loading system supports continuous data flow: taking files from the NCBI FTP site, preliminary processing, parsing, loading to the Sybase PubMed database, dumping new records from PubMed to MedLine on mainframe. C++ classes were developed and implemented for the loading system. All actions are documented by the correspondent logfiles.
Also worked on some miscellaneous tasks for the PubMed bioinformatic retrieval system. Created a special dictionary, which contains major SGML entities according to International Standard ISO 8879-1986. Using UNIX shared memory designed and implemented PubMed Journal Server. As well as created a number of CGI programs, which provide WWW interface for the database administrator to maintain data in PubMed.
