  1. HDF Studio John Readey The HDF Group

  2. About Me (briefly) • IBM/Portable Graphics: 1990-1997 • 3D graphics – OpenGL, Open Inventor • DEC/Intel: 1997 – 2006 • Developed Intel Array Visualizer (first exposure to HDF!) • Amazon.com: 2006-2014 • FBA – Fulfillment for 3rd party sellers • AWS – Diagnostic Tools • The HDF Group: 2014 - ? • Tools & Cloud Technology

  3. What is HDF Studio? • A set of server and client side software components that enables people to visualize and understand their data and to share that knowledge with others • Details: • Focus on large structured datasets (HDF5) • Share not only the data, but representations of data • Utilize Web Standards (REST, JSON, Oauth) • Highly scalable (by collection size and number of users)

  4. Limitations of HDFView as a Platform • Data is shared by copying files (e.g. through FTP) • Views (graphs) are not persisted • Limited ability to handle large data sets • Does not address collections (related sets of files) • Extending (i.e. plugin architecture) is hard

  5. HDF Studio Architecture

  6. HDF Studio Components • Cloud based repository for data • REST API for reading and writing data • OPeNDAP support • HDF5 library modified to use REST API • Studio Desktop App – view and edit data local or remote • Plugin model – extensions to Studio can be pulled in dynamically from common repository

  7. Challenges… • Authentication and permission model • Let people keep data private or share with others • Performance • Goal – comparable to local file system performance • Scalability • Support arbitrary numbers of users accessing service • Arbitrary large data collection size • Reliability • Service should work almost always (99.99% uptime)

  8. Where we are now… • Just getting started! • Welcome: • Comments • Cool ideas • Areas for collaboration • Intent is to release updates incrementally
