[jira] Created: (UIMA-1969) Add support for external resources
hosted on an http server
Add support for external resources hosted on an http server
-----------------------------------------------------------
Key: UIMA-1969
URL: https://issues.apache.org/jira/browse/UIMA-1969
Project: UIMA
Issue Type: New Feature
Components: Core Java Framework
Affects Versions: 2.3.1SDK
Reporter: Jörn Kottmann
Currently external resources for an Analysis Engine can only be loaded from the file system. This is useful
for many use cases in which the resources are almost static and rarely change. In our scenario the resources
are updated frequently and hosted on a central server. The server could expose a file system over the network
via NFS or windows file sharing, but it seems to be more intuitiv and easier to just distribute the resources via http.
In order to do that the resource loading must be extended to also support resource which are available via
http. It seems that the current code for the file URLs can be easily extended to also allow http resources.
According to the documentation it uses URL.openStream and forbids http URLs which would be supported
by that method.

Marshall Schor commented on UIMA-1969:
--------------------------------------
There are two impls of DataResource interface.
* ConfigurableDataResource_impl
* DataResource_impl
Both are initialized with a ResourceSpecifier, an instance of:
* ConfigurableDataResource_impl -- ConfigurableDataResourceSpecifier
* DataResource_impl - FileResourceSpecifier
Neither of these specifiers actually requires that the URL be a file.
DataResource_impl first attempts to create the URL from the spec; only if that fails does it attempt to construct a URL based on treating the spec as a file.
The ConfigurableDataResource_impl does the same thing, but doesn't attempt to construct a URL based on treating the spec as a file name.
So - this might work already, and maybe the Javadocs need to be fixed?

-------------------------------------
Sorry it took me a few days. I tested it now with UIMA-AS 2.3.1 RC4 and it can just load resources from an http server out of the box.
To close this issue we need to update the documentation.
