[x3d-public] X3D Audio meeting minutes, updated sound component, XML/java/python/turtle/validator updates

Mon Oct 26 05:14:39 PDT 2020

Re:  nashorn branch

1.  Suggest that John create a GraalVM build for X3DJSONLD.

2. Possibly look for another implementation of ECMAScript in Java (Rhino?)

3.  Suggest deprecation of branch as people move to OpenJDK 15

Re: node branch

1.  Continue supporting node branch, update example filenames.

2.  Run tests and examine results.

3. Enhance X3dToNodeJS.xslt as needed. (Don)

4. Examine potential broken Java contracts as found with pyjnius.

5.  Upgrade node.js java module to go along with OpenJDK 15.

Re: John’s health

1. Resumed relaxation has improved John’s RSI.

2. Suggest minimal typing, RFI on alternatives (Jeff Gray and Eclipse?),
particularly a NetBeans solution if X3D-Edit continues down NetBeans path.

3. Also investigate Git Desktop or netbeans git.

4. Consider resuming fish oil, aspirin.

John
