Portable Document Format Nuclear Data Library

Current needs of nuclear science and technology include  complete, well-documented and easily-verifiable nuclear data records.  The complete data records require supporting  nuclear bibliography, presently stored  in dedicated libraries, in addition, to actual data.  The complementary library materials often represent a bottleneck for the worldwide support of research, and nuclear data compilation, evaluation and dissemination activities. The evolution of Web and nuclear database technologies at the Brookhaven National Laboratory and International Atomic Energy Agency  paved an avenue for creation of a portable   data library using the  Experimental nuclear reaction data (EXFOR)  and Nuclear Science References (NSR) database contents. Bibliography materials in the both organizations were scanned in a Portable Document Format (PDF) and  stored in  relational databases.

The common scope of relational databases that includes text, numbers and date formats was broadened to accommodate the large volumes of original nuclear data publications. The PDF publication files were converted into Binary Large Objects (BLOB) and added to relational database tables.  The Web interfaces for authorized access to the PDF Nuclear Data Library (PDF NDL)  contents were implemented at the   U.S. National Nuclear Data Center, {\it https://www.nndc.bnl.gov} and IAEA Nuclear Data Section, {\it https://www-nds.iaea.org}. The principles of the  Web and database applications development are described.  New  capabilities for the data sets curation, preservation  and worldwide dissemination are given.
