+#Pubmed Mapping
+This section describes the mapping implemented for [MEDLINE/PubMed](https://pubmed.ncbi.nlm.nih.gov/).
+
+Collection
+---------
+The native data is collected from [ftp baseline](https://ftp.ncbi.nlm.nih.gov/pubmed/baseline/) containing XML with 
+the following [shcema](https://www.nlm.nih.gov/bsd/licensee/elements_descriptions.html) 
+
+
+Parsing
+-------
+The resposible class of parsing is [PMParser](./scaladocs/#eu.dnetlib.dhp.sx.bio.pubmed.PMParser) that generates 
+an intermediate mapping of PubMed Article defined [here](/apidocs/eu/dnetlib/dhp/sx/bio/pubmed/package-summary.html)
+
+
+Mapping
+-------
+
+The table below describes the mapping from the XML Native to the OAF mapping

+| ----------- | ----------- | ----------- |
+| //PMID      | pid         | classid = classname = pmid

+|//PMID | instance/PID | Map the pmid also in the pid in the instance |
+| //ArticleId[./@IdType="doi"   | instance/alternateIdentifier  |classid = classname = doi
+|//PMID | instance/URL | prepend to the PMId the base url https://pubmed.ncbi.nlm.nih.gov/
+| //PubmedPubDate | instance/Dateofacceptance | apply the function GraphCleaningFunctions.cleanDate before assign it
