Distribution of XML to non-XML documents, including OA status, by publication year. This figure shows the distribution of XML to non-XML documents available in Europe PMC including OA status by publication year. The section tagger operates on the full text articles provided in XML format only. The figure shows that XML-formatted documents make up close to 100% of content available in Europe PMC that has been published in the last 7 years, which means that only a small minority of recent articles available in Europe PMC are missed.
