The primary goals of this project for the period of October 1, 2015 and September 30, 2020 are:

Maintenance and quality assurance for HDF4 and HDF5 libraries and utilities

Maintenance includes making minor feature changes to address EOSDIS requirements, correcting errors, keeping the software, test suites, configurations, and documentation current, and conducting periodic releases of the software. Quality assurance involves upgrading and extending software testing, reviewing and revising documentation, improving the software development process, and strengthening software development standards.

Evolving the HDF4 and HDF5 library and utilities to meet new NASA EOS requirements

Two focused areas include enhancing HDF5 backward and forward compatibility support and developing tools to improve the accessibility and usability of data stored in HDF5.

Support activities for NASA HDF data providers and data users and for the EOSDIS Core System (ECS)

As EOSDIS matures and increasing amounts of data are archived, current users will be joined by users with an ever-broadening range of applications. Usability and accessibility of EOS data are not only crucial to global climate change research but also become increasingly important for policy makers, educators, the private sector and the general public. The HDF Group will provide continuing support in the form of the HDF Help Desk, workshops, training, and documentation. The HDF Group will also work with the ECS, DAACs, and other data centers to improve usability and accessibility of EOS data by means of on-site visits, consulting, and tutorials.

Support for data and metadata interoperability, standards, and models

As more and more scientific data sets are collected, it is vitally important that these data can be easily analyzed across instruments, data products, and disciplines. The HDF Group provides support and expertise in ensuring metadata interoperability, compliance with evolving standards and conventions, and representing NASA's interests within international standards organizations.

Integration with complementary technologies and application domains

In order to operate well with HDF-EOS technologies, we need to make sure complementary technologies perform efficiently together, and that the HDF-EOS library and tools use HDF as effectively as possible. Other technologies, such as OPeNDAP, netCDF, XML, and GIS, can add tremendous value when effectively integrated with HDF. The HDF Group assists in these efforts by helping integrate these and other emerging technologies with HDF tools and APIs.
