Heidi McClure created SOLR-12534: ------------------------------------ Summary: Add Edge Labels for Graph exports to GraphML to allow imports to Gephi Key: SOLR-12534 URL: https://issues.apache.org/jira/browse/SOLR-12534 Project: Solr Issue Type: New Feature Security Level: Public (Default Security Level. Issues are Public) Components: Response Writers Affects Versions: 7.4, 7.3.1, 7.3, 7.2.1, 7.2 Environment: Hello,
I am trying to export graph data from a Solr index (version 7.2) in a format that can be imported to Gephi for visualization. I'm getting close! Is there a way to add edge labels to the exports from this type of command (see curl command that follows and sample outputs)? Thanks in advance, -heidi Based on the examples found here: [https://lucene.apache.org/solr/guide/7_2/graph-traversal.html] , this is working in my GDELT-based data set query request: curl --data-urlencode 'expr=nodes(gdelt_graph, nodes(gdelt_graph, walk="POLICE->Actor1Name_s", trackTraversal="true", gather="Actor2Name_s"), walk="node->Actor1Name_s", scatter="leaves,branches", trackTraversal="true", gather="Actor2Name_s")' [http://mymachine:8983/solr/gdelt_graph/graph] Output is like this (just a subset): <?xml version="1.0" encoding="UTF-8"?> <graphml xmlns="http://graphml.graphdrawing.org/xmlns" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://graphml.graphdrawing.org/xmlns [http://graphml.graphdrawing.org/xmlns/1.0/graphml.xsd]"> <graph id="G" edgedefault="directed"> <node id="POLICE"> <data key="field">node</data> <data key="level">0</data> </node> <edge id="1" source="BANGLADESH" target="POLICE"/> <node id="HOSPITAL"> <data key="field">Actor2Name_s</data> <data key="level">1</data> </node> <edge id="2" source="POLICE" target="HOSPITAL"/> <node id="UNITED STATES"> <data key="field">Actor2Name_s</data> <data key="level">1</data> </node> <edge id="3" source="UNITED STATES" target="UNITED STATES"/> <edge id="4" source="AFRICA" target="UNITED STATES"/> <edge id="5" source="POLICE" target="UNITED STATES"/> And I'd like to have a key for label and the data tag on the edges so that I can get the Labels into Gephi. Does anyone know if this can be done? Below is example of what I mean. Notice the key for label at the top of the file and the "This is an edge description" entries on two of the edges (ids 1 and 2). <?xml version="1.0" encoding="UTF-8"?> <graphml xmlns="http://graphml.graphdrawing.org/xmlns" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://graphml.graphdrawing.org/xmlns [http://graphml.graphdrawing.org/xmlns/1.0/graphml.xsd]"> <key id="label" for="edge" attr.name="label" attr.type="string"/> <graph id="G" edgedefault="directed"> <node id="POLICE"> <data key="field">node</data> <data key="level">0</data> </node> <edge id="1" source="BANGLADESH" target="POLICE" label="foo"> <data key="label">This is an edge description.</data> </edge> <node id="HOSPITAL"> <data key="field">Actor2Name_s</data> <data key="level">1</data> </node> <edge id="2" source="POLICE" target="HOSPITAL"> <data key="label">This is an edge description.</data> </edge> <node id="UNITED STATES"> <data key="field">Actor2Name_s</data> <data key="level">1</data> </node> <edge id="3" source="UNITED STATES" target="UNITED STATES"/> <edge id="4" source="AFRICA" target="UNITED STATES"/> <edge id="5" source="POLICE" target="UNITED STATES"/> Reporter: Heidi McClure Fix For: 7.5 Please add the ability to export edge labels to the GraphML export API. In the environment section is the email I sent to solr-users where they suggested adding an issue to request this capability be added - they also said it would be an easy change to make. The change is minor and would possibly be to this class: org.apache.solr.response.GraphMLResponseWriter or might be an extension to that class. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
