STI Software Appropriate for Announcement

Scientific and technical computer software is a type of STI managed by the DOE Office of Scientific and Technical Information (OSTI). A new model for scientific software collaboration, archiving, and dissemination called DOE CODE replaced OSTI's software center, the Energy Science and Technology Software Center (ESTSC).

DOE national laboratories and other DOE facilities/contractors who have developed and/or modified software during work supported by DOE or during work carried out for others at DOE facilities are required to announce the software with the appropriate announcement record to DOE CODE, if the software meets the following criteria:

  • the software meets the definition of STI;
  • the software is known or expected to be useful inside or outside the DOE community, or is not specific to the originating site; and
  • a stable, usable, documented version of the software exists (i.e., the software is not under initial development);
  • the software has undergone all appropriate reviews for sensitivity and export control.

Exclusions. Software that meets the following criteria need not be announced:

  • operational systems software that is site-specific, unique to a particular hardware, or necessary to ensure the fundamental operability of automated data processing equipment, whether supplied by the manufacturer of the system hardware or others;
  • computer software programs developed and/or modified during work carried out for others at DOE facilities that are specifically excluded in the agreement under which the non-DOE funded work was performed;
  • software generated under the auspices of the Energy Information Administration; and
  • specific software used by power administrations for the operation, control, planning, and modeling of electric power transmission systems and the interconnected utilities; however, modifications/enhancements to portions of this software that are not an integral part of the whole and have potential application outside the power administrations should be announced.

Software Categories

Different categories of software have different distribution requirements, limitations and appropriate distribution channels, which are defined in the Software Categories table. Scientific and technical software will be disseminated by the Sites, according to the applicable distribution limitation.
