Hi [~stain], 

_This is just an update:_ According the GSoC timeline, mentors are reviewing 
proposals, and I submitted my proposal successfully with the changes you 


> GSOC: Use arcp:// URIs in RO Bundle
> -----------------------------------
>                 Key: TAVERNA-1037
>                 URL: https://issues.apache.org/jira/browse/TAVERNA-1037
>             Project: Apache Taverna
>          Issue Type: New Feature
>          Components: Taverna Language
>         Environment: Java, HTTP
>            Reporter: Stian Soiland-Reyes
>            Priority: Major
>              Labels: RFC, gsoc2018, java, uri
> This is a project idea for [Google Summer of 
> Code|https://summerofcode.withgoogle.com/] (GSOC). To discuss this or other 
> ideas with your potential mentor from the Apache Taverna project, sign up and 
> post to the

> The 
> [ro-bundle|https://github.com/apache/incubator-taverna-language/tree/master/taverna-robundle]
>  module of Taverna Language currently uses app:// URIs in its Java 
> [FileSystem|https://docs.oracle.com/javase/8/docs/api/java/nio/file/FileSystem.html]
>  URIs and thus also in its RDF loading.
> This was in accordance with [RO bundle 
> spec|https://researchobject.github.io/specifications/bundle/#absolute-uris] – 
> however the app:// URI scheme has been since abandoned.
> The arcp URI scheme has been proposed as an alternative to describe paths 
> within an archive (e.g. ZIP file): 
> [https://tools.ietf.org/id/draft-soilandreyes-arcp-03.html] (This 
> Internet-Draft is progressing towards an RFC)
> This proposal suggests to modify RO Bundle to use arcp:// URIs – but not just 
> modify app://bf5a0cab-86d7-40da-b588-1ce4953ae13d/ to 
> arcp://uuid,bf5a0cab-86d7-40da-b588-1ce4953ae13d/ - but to support the other 
> mechanisms suggested by arcp in 
> [https://tools.ietf.org/id/draft-soilandreyes-arcp-03.html#rfc.section.4.1]
> That is, it should be possible to open an RO Bundle from a fixed URL as 
> identifier, or using its sha256 checksum in readonly mode.
> It should also be possible to lookup an RO Bundle URI from a .well-known 
> endpoint as defined in 
> [https://tools.ietf.org/id/draft-soilandreyes-arcp-03.html#rfc.section.4.4]
> Extensions to this project could be to add a Java URL handler so that URLs 
> from an opened RO Bundle file system also can be used as java.net.URLs. Also 
> it could develop a new arcp-java module similar to the reference Python 
> implementation https://pypi.python.org/pypi/arcp
> Prospective students are expected to participate in the Apache [Taverna 
> community|https://taverna.incubator.apache.org/community/lists.html#devtaverna]
>  - but are also welcome to join the [IETF |https://www.ietf.org]review 
> process  in reviewing or improving the arcp Internet-Draft to progress it 
> towards RFC.
> Suggested mentor: Stian Soiland-Reyes
