+#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

+|//PublicationType | InstanceType  | If the article contains the typology **Journal Article** then we apply this type else We have to find a terms that match the vocabulary otherwise we discard it
+|//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/
