The CAS translator is outdated now. Once there is a new stable version ready, we need to update the reflection calls for proper usage in converters.

MathMLTools will be the parent repository (and parent maven project) for all MathML related tasks.

It is planned as multi-module maven project. The following tasks have to be done

• build parent pom in MathMLTools repo
• move MathMLConverters and MathMLSim to this repo
• move converters from mathosphere/pomlp to MathMLConverters
• refactor MathMLTools itself into other submodules (MathMLTools in MathMLTools is confusing)
• Create a README to give an overview of the submodules
• Solve snapshots by create a deploy system to maven central (see #12)
• Update related projects! (Known dependencies: vmext-demo) <= Update: Not needed since we use a new version 1.0.0 for the refactored project -> there will be no conflicts)

@physikerwelt Could it be that you forget to update the POM-versions (or we forget to specify that in travis)? vmext-demo depends on v. 2.0.2
https://github.com/ag-gipp/vmext-demo/blob/9a27896a1242d823d13f1161f49066c801c218ad/pom.xml#L61-L65

but all poms are still on 2.0.2-SNAPSHOT:
https://github.com/ag-gipp/MathMLTools/blob/77c69b6366a5b8720796d1cd9d155ba26c2f1b20/pom.xml#L9

Also, the releases are already on 2.0.4: https://github.com/ag-gipp/MathMLTools/tree/2.0.4
as well as maven central: https://search.maven.org/artifact/com.formulasearchengine.mathmltools/mathmltools/2.0.4/jar

Something we missed in .travis.yml?

I was wondering if we should add libraries that can be used independently of Java and Maven. The idea came up since we are facing same or similar issues with MML in VMEXT (see gipplab/vmext#28).

I'm not sure if it is worth to provide a whole javascript based API of our MathMLTools project (maybe in distant future). But I think a good idea would be a library of useful XPath commands. Perhaps a YAML file accessible from one of our servers.

What do you think @physikerwelt @vstange?

store the config in a file

• create test case for EnrichedMathMLTransformer with the following input

<math xmlns="http://www.w3.org/1998/Math/MathML" display="block" alttext="a">
  <semantics>
    <mi>a</mi>
    <annotation encoding="application/x-tex">a</annotation>
  </semantics>
</math>

• update endpoint /math/mathoid in vmext-demo and recheck

Calling LaTeXML server does not work anymore. Thus multiple tests fail due to 404 and other errors. Furthermore, a simple fix (changing URL) does not work, since it seems the new server endpoints are different.

Currently, I try to figure out why curl request work but RestTemplate calls does not work. One possible problem might be that RestTemplate is old and as of newer versions of org.springframework.web will become deprecated as well. A better alternative should be WebClient (introduced with 5.0, see here).

I don't know how to setup an auto deployment for this multi-module project now. Is it enough to enter all settings in the parent pom? Do we need to add deployments to each module?

The scanFormulaNode can't recognize formulas not containing "apply"- or "mrow"-nodes. The mistake is based on my false assumption that there should always be a surrounding element.

Instead, the method should examine the semantic elements more closely.

The CAS translator tries to load resources from the libs folder.
In its current state, the folder is needed as a subfolder of the project.
As a workaround, I created a linked folder to the original folder which solves the problem. However, I should implement another solution for this.

Currently one needs to know before parsing the expression if there are prefixes in the MML string or not. This is very unhandy and should be fixed.

A nice feature would be to add and remove namespace prefixes on the fly.

No more snapshot versions in the master branch. Instead using more minor version numbers.

Provide the following features to makes it easier to use the API:
Converters:

• Scripts for downloading and install sources of converters (because of license problems we will not provide the tools directly)

Gold:

• Easier switch between local and remote mode (explain config file)
• Download entire MathMLBen and store once (provide function)

Sim:

• Add tree edit distance (RTED) from mathosphere

The string2Doc in XMLHelper ignores the namespaceAwareness parameter.

 /**
     * Helper program: Transforms a String to a XML Document.
     *
     * @param inputXMLString     the input xml string
     * @param namespaceAwareness the namespace awareness
     * @return parsed document
     */
    public static Document string2Doc(String inputXMLString, boolean namespaceAwareness) {
        try {
            return XmlDocumentReader.parse(inputXMLString, false);
        } catch (IOException | SAXException e) {
            log.error("Cannot parse XML string.", e);
            return null;
        }
//        try {
//            DocumentBuilder builder = getDocumentBuilder(namespaceAwareness);
//            InputSource is = new InputSource(new StringReader(inputXMLString));
//            is.setEncoding("UTF-8");
//            return builder.parse(is);
//        } catch (SAXException | ParserConfigurationException | IOException e) {
//            log.error("cannot parse following content\n\n" + inputXMLString);
//            e.printStackTrace();
//            return null;
//        }
    }

Reason: It looks like coveralls doesn't recognize JUnit 5.
