Convert XML to RDF Online

Paste an XML table below, edit it if you need to, and get RDF back. The conversion runs in your browser, so nothing is uploaded, there is no size limit and there is no signup.

From a page

The only part of this site that uses a server. The address is sent to it so the page can be fetched, because a browser is not allowed to fetch someone else's page itself. Your own files are never involved.

Nothing here is uploaded. The parsing happens on this page.

Paste or upload something above and it will appear here.

What XML is

XML marks up data with nested named tags and optional attributes. It is verbose, strict about being well-formed, and can carry a schema that says what shape a document must have.

Enterprise integrations, government data feeds, RSS, SOAP services and older document formats.

What RDF is

RDF in Turtle syntax: subject, predicate, object triples describing each row.

Linked data and semantic web projects.

What changes when you convert XML to RDF

The first repeating element is treated as the rows. Attributes are read alongside child elements and prefixed so they do not collide with a same-named tag. Nesting one level deep becomes dotted column names; deeper structures are kept as text.

Each row becomes a subject with one predicate per column, under an example.org namespace you will want to change.

What carries over from XML to RDF

One property of the XML has no home in RDF, and it is worth knowing which before you convert.

RDF wants a type for each column, and XML does not record one, so each column is typed from what its values look like. A column of digits that should stay text - a zip code, a phone number, a leading-zero id - is the usual thing to check afterwards.

An empty cell and a missing one are the same thing in RDF, so a null and an empty string in the XML both come out blank and can no longer be told apart.

The identifier 007 comes out of the RDF as 007. Reading it as a number would have made it 7, and an id that changes value is worse than one that stays text.

The role "Analyst, data" survives with its comma, in one cell rather than split across two. That is the first thing to check in any converted table, and the usual place a RDF file goes wrong.

The quotes around Jonah "Jo" Pryce are escaped with a backslash in the RDF.

A worked example

Three rows of staff data, with an identifier that has a leading zero, a value containing a comma, a value containing quotes and one blank cell. Those are the four places formats disagree, so they are the four places to look.

Questions

How do I convert XML to RDF?

Paste your XML into the box above or drop the file onto it. Check the table in the grid, then copy or download the RDF from the output panel. It takes one step and the data never leaves your browser.

Is there a limit on file size?

No. The work happens on your own machine, so the limit is your machine's memory rather than an upload cap. A file with tens of thousands of rows converts in a second or two.

Is my data uploaded anywhere?

No. The parsing and generating are done by JavaScript running on this page. You can watch the network tab while you convert and see that nothing is sent.
