Stephen Mallette updated TINKERPOP-848: --------------------------------------- Environment: (was: All) > Support default attribute values in GraphMLReader > ------------------------------------------------- > > Key: TINKERPOP-848 > URL: https://issues.apache.org/jira/browse/TINKERPOP-848 > Project: TinkerPop > Issue Type: Improvement > Components: io > Affects Versions: 3.0.2-incubating > Reporter: Pavel Klinov > Priority: Trivial > Original Estimate: 2h > Remaining Estimate: 2h > > Looking at the code of GraphMLReader I see that it doesn't support default > values of attributes, which are allowed by the GraphML spec. This is a bit > annoying especially if the input defines default values for attributes which > are used for mandatory data, e.g. edge labels. > One small example is the sample graph at [1]. "d_e" is the label attribute > with a default value. There're <edge .. /> elements w/o body later in the > document and reading those will throw a "java.lang.IllegalArgumentException: > Label can not be null" exception (if the vendor considers edge labels > mandatory). > I'd personaly squash both keyIdMap and keyTypesMap into a single String -> > AttrInfo map, where AttrInfo would contain information about the data > attribute name, type, and the default value. > [1] http://www.eecs.wsu.edu/~yyao/DirectedStudyI/Datasets/AS/sample.graphml -- This message was sent by Atlassian Jira (v8.3.4#803005)
