The com.mikahimself.dita2json plugin is a simple DITA-OT plugin that converts DITA topics to a simple JSON format, retaining the content in basic HTML format like so:
[
{
"title": "Topic 1",
"text": "<p>Content goes here.</p>",
"type": "concept",
"url": "topic1.htm"
},
{
"title": "Topic 2",
"text": "<p>Other content goes here.</p>",
"type": "concept",
"url": "topic2.htm"
}
]
