dataset export to SVG

[craigsapp]

Related to this function:

https://github.com/rism-digital/verovio/blob/develop/src/svgdevicecontext.cpp#L991-L1003

void SvgDeviceContext::AppendAdditionalAttributes(Object *object)
{
    std::pair<std::multimap<ClassId, std::string>::iterator, std::multimap<ClassId, std::string>::iterator> range;
    range = m_svgAdditionalAttributes.equal_range(object->GetClassId()); // if correct class name...
    for (std::multimap<ClassId, std::string>::iterator it = range.first; it != range.second; ++it) {
        ArrayOfStrAttr attributes;
        object->GetAttributes(&attributes);
        for (ArrayOfStrAttr::iterator iter = attributes.begin(); iter != attributes.end(); ++iter) {
            if (it->second == (*iter).first) // ...and attribute exists in class name, add it to SVG element
                m_currentNode.append_attribute(("data-" + it->second).c_str()) = (*iter).second.c_str();
        }
    }
}

Is there method for exporting dataset parameters from MEI into SVG?

Or is that function related to the previous one in the file (and for internal use only):

void SvgDeviceContext::AppendIdAndClass(std::string gId, std::string baseClass, std::string addedClasses, bool primary)

SvgDeviceContext::AppendAdditionalAttributes is for passing --svg-additional-attribute * <s>.

See in https://book.verovio.org/toolkit-reference/toolkit-options.html?q=attribute#input-and-page-layout-options:

• Add additional attribute for graphical elements in SVG as "data-*", for example, "note@pname" would add a "data-pname" to all note elements

If you want something added to @class, then you can use the MEI @type attribute. As far as I remember, that one is always added to the SVG. The SvgDeviceContext::AppendIdAndClass is internal.
