What UML tool is this file from?

Question

I've got a bunch of *.uml files in one legacy project that look like this:

<?xml version="1.0" encoding="UTF-8"?> <Diagram> <ID>JS</ID> <OriginalElement>...</OriginalElement> <nodes /> <settings layout="Hierarchic Group" zoom="0.8528951486697965" x="288.0" y="309.5" /> <SelectedNodes /> <Categories> <Category>Fields</Category> </Categories> <SCOPE>All</SCOPE> <VISIBILITY>PUBLIC</VISIBILITY> </Diagram>

Any idea which tool generated this?

Answer 1

These files are IntelliJ IDEA (Ultimate Edition, not Community Edition) diagram files, used store UML diagrams generated by IntelliJ.

Here is an example shown in IntelliJ:

Here what the .uml file contains:

<?xml version="1.0" encoding="UTF-8"?>
    <Diagram>
    <ID>JAVA</ID>
    <OriginalElement />
    <nodes>
        <node x="-317.5" y="-101.0">com.artechra.Detail</node>
        <node x="-320.5" y="-195.0">com.artechra.Master</node>
    </nodes>
    <notes />
    <edges>
        <edge source="com.artechra.Master" target="com.artechra.Detail">
            <point x="0.0" y="0.0" />
            <point x="0.0" y="0.0" />
        </edge>
    </edges>
    <settings layout="Hierarchic Group" zoom="1.0" x="0.0" y="0.0" />
    <SelectedNodes />
    <Categories />
    <SCOPE>All</SCOPE>
    <VISIBILITY>private</VISIBILITY>
</Diagram>

According to the text that appears in each diagram, it's all "powered by" yFiles which may well be the generic markup format.
