+Motivation
+==========
+
+ * SECoP motivation proposal
+ * simple, inclusive and self describing
+ * write drivers only once
+ * different institutes wrote their own driver collection which fulfils all their needs and it works reliable 
+ * as secondary effect the standard drivers still can be used so their are well tested and may become more reliable
+
+SECoP
+-----
+
+The SECoP (Sample Environment Communication Protocol) is an Inclusive, Simple and Self Explaining (ISSE) communication protocol.
+Inclusive means, that facilities can use this protocol and don't have to change their work flow (rewrite drivers completely or organize and handle hardware in a specific way to fulfil SECoP requirements).
+Simple means it should be easy to integrate and to use.
+Self Explaining means that with SECoP, not only the pure data is transported. It also transports meta data, which allows environment control software to configure by itself.
+The benefit of SECoP will be to circulate expensive devices between different facilities with minimised effort for configuration and integration.
+This should result in an increased utilisation of expensive equipment.
