+### Attachment Data
+
+**Responsible dropbox:**
+[QBiC-register-exp-proj-attachment](drop-boxes/register-attachments-dropbox)
+
+**openBIS structure:**
+
+Attachments are attached to the Q_PROJECT_DETAILS experiment type and its sample type Q_ATTACHMENT_SAMPLE.
+
+**Expected data structure**
+The data structure needs to be a root folder, containing a file `metadata.txt`.
+
+Incoming structure overview:
+
+```
+|-<anything> (top level folder name, normally a time stamp of upload time)
+    |
+    |- metadata.txt
+```
+
+**Expected metadata**
+Metadata is expected to be denoted in line-separated key-value pairs, where key and value are separated by a '='. The following structure/pairs are expected:
+
+```
+user=<the (optional) uploading user name>
+info=<short info about the file>
+barcode=<the sample code of the attachment sample>
+type=<the type of attachment: information or results>
+```
+The code of the attachment sample is built from the project code followed by three zeroes, conforming to the regular expression "Q[A-Z0-9]{4}000", e.g. QABCD000.
+
+See code examples:
+https://github.com/qbicsoftware/attachi-cli/blob/master/attachi/attachi.py#L63
