NIAC2014 CodeCamp

The code camp allows existing NeXus developers to meet and work together on developing software or resolving particular NeXus design issues.

See NIAC2014 for administrative details about this meeting.

Planned Schedule (subject to change)

Topics to be Considered

A subset will be chosen on the first day of the meeting.

Walk through

• Issues posted on the NeXus GitHub repository

• Proposals and other topics listed on the [Discussions] (Discussions.html “wikilink”) page

• Close issues that are of minor importance and not of particular concern to anybody and not likely to be resolved any soon.

Choose topics from the preliminary list below:

• Procedural questions:

  • How to organize proposals and discussions

  • How to remove ballast, when to break compatibility, versioning and validation

• Fundamental design issues:

  • Clarify rank specification

    • related to #266: implement difference in rules between base classes and application definitions

  • Discuss NeXus interfaces

  • How to avoid name clashes during future extensions of the Nexus standard

  • Optional contents in application definitions?

  • Discuss lightweight tags versus application definitions

  • Rules for multi file NeXus files

• Class specifications:

  • NXformula?

  • NXdata: Assigning axes to data once more again

  • Prepare contributed definitions for ratification

• Work on software:

  • validation tools (nxvalidate or NXvalidate): state (cf #169/defs, #251/defs, #300/defs, #363/code), further development, WWW service, use of NeXpy/Python-API for validation

  • New NAPI release?

  • #230: use cmake to build Sphinx documentation
