+# UniProtKB/Swiss-Prot
+
+this section describes the mapping implemented for [UniProtKB/Swiss-Prot](https://www.uniprot.org/).
+The whole dump can be downloaded by [here](https://www.uniprot.org/help/downloadss) the Reviewed (Swiss-Prot).
+
+From this Dump we extract only the protein linked to a pubmed Publication.
+
+
+## Entity Mapping
+
+The table below describes the mapping from the TEXT metadata format to the OpenAIRE Graph dump format.
+You can check an example of the text metadata [here](https://rest.uniprot.org/uniprotkb/A0A0C5B5G6.txt)

+| `id`                           | `LINE Starts with AC`  | id in the form `uniprot_____::md5(id)`|
+| `pid`                          | `LINE Starts with AC`  |  example `AC   A0A0C5B5G6;`  classid=classname=`uniprot`  the vaue is the text after `AC`  |
+| `publicationdate`           | `LINE START WITH DT containg text integrated into UniProtKB/Swiss-Prot`                                 | clean and normalize the format of the date to be `YYYY-mm-dd` |
