-------------------------------------
Summary: RO library does not recognize the history
Key: TAVERNA-842
URL: https://issues.apache.org/jira/browse/TAVERNA-842
Project: Apache Taverna
Issue Type: Bug
Components: Taverna Language
Environment: using following version:
<groupId>org.apache.taverna.language</groupId>
<artifactId>taverna-robundle</artifactId>
<version>0.15.1-incubating-SNAPSHOT</version>
Reporter: martin scharm
The {{bundle.getManifest ().getHistory ()}} method seems to always return an
empty list, even if there is a history defined in the file.
Small example that just dumps out the manifest's content and checks if there is
a file {{.ro/evolution.ttl}}:
{code:title=Example.java|borderStyle=solid}
try (Bundle bundle = Bundles.openBundleReadOnly (file.toPath ())) {
Manifest mf = bundle.getManifest ();
Path manifest = bundle.getRoot ().resolve (".ro/manifest.json");
for (String line : Files.readAllLines(manifest,
Charset.forName("UTF-8")))
System.out.println(line);
Path evolution = bundle.getRoot ().resolve (".ro/evolution.ttl");
System.out.println ("evolution exists: " + Files.exists (evolution));
System.out.println ("bundle knows about the evolution: " +
mf.getHistory ().size () + ": " + mf.getHistory ());
}
{code}
results in:
{noformat}
{
"@context" : [ "https://w3id.org/bundle/context"; ],
"id" : "/",
"manifest" : [ "manifest.json" ],
"history": "evolution.ttl"
}
evolution exists: true
bundle knows about the evolution: 0: []
{noformat}
So the manifest defines the history being stored in {{evolution.ttl}}, the file
{{.ro/evolution.ttl}} exists, but I'm not able to retrieve it via
{{mf.getHistory ()}}.
