+### hsadminNg fachliches Glossar
+
+<!--
+Currently, this business glossary is only available in German because in many cases, 
+the German terms are important for comprehensibility for those using this software.
+-->
+
+Dieses ist eine Sammlung von Fachbegriffen, die in diesem Projekt benutzt werden.
+Ebenfalls aufgenommen sind technische Begriffe, die für Benutzer für das Verständnis der Schnittstellen nötig sind.
+
+Falls etwas fehlt, bitte Bescheid geben.
+
+
+#### Partner
+
+In diesem System ist ein _Partner_ grundsätzlich jeglicher Geschäftspartner der _Hostsharing eG_.
+Dies können grundsätzlich Kunden, siehe [Debitor](#Debitor), wie Lieferanten sein.
+Derzeit sind aber nur Debitoren implementiert.
+
+Des Weiteren gibt es für jeden _Partner_ eine fünfstellige Partnernummer mit dem Prefix 'P-' (z.B. `P-123454`)
+sowie Zusatzinformationen (z.B. Registergerichtnummer oder Geburtsdatum), die zur genauen Identifikation benötigt werden.
+
+Für einen _Partner_ kann es gleichzeitig mehrere [Debitoren](#Debitor) 
+und zeitlich nacheinander mehrere [Mitgliedschaften](#Mitgliedschaft) geben.
+
+Partner sind grundsätzlich als ist [Relation](#Relation) der Vertragsperson mit der Person _Hostsharing eG_ implementiert.
+
+
+### Debitor
+
+Ein `Debitor` ist quasi ein Rechnungsempfänger für einen [Partner](#Partner).
+
+Für einen _Partner_ kann es gleichzeitig mehrere [Debitoren](#Debitor) geben, 
+z.B. für spezielle Projekte des Kunden oder verbundene Organisationen.
+
+Des Weiteren gibt es für jeden _Partner_ eine fünfstellige Partnernummer mit dem Prefix 'P-' (z.B. `P-123454`)
+sowie Zusatzinformationen (z.B. Registergerichtsnummer oder Geburtsdatum), die zur genauen Identifikation benötigt werden.
+
+Debitoren sind grundsätzlich als ist [Relation](#Relation) der Vertragsperson mit der Person des Vertragspartners implementiert.
+
+
+#### Relation
+
+Eine _Relation_ ist eine typisierte und mit Kontaktdaten versehene Beziehung einer (_Holder_)-Person zu einer _Anchor_-Person.
+
+Eine Relation ist eine Art Geschäftsrolle, wir haben hier aber keinen Begriff mit 'Rolle' verwendet,
+weil 'Role' (engl.) zu leicht mit der [RBAC-Rolle](#RBAC-Role) verwechselt werden könnte.
+
+Die _Relation_ ist auch ein technisches Konzept und gehört nicht zur Domänensprache.
+Dieses Konzept ist jedoch für das Verständnis der ([API](#API)) notwendig.
+
+
+#### Ex-Partner
+
+Ex-Partner bilden [Personen](#Person) ab, die vormals [Partner](#Partner) waren.
+Diese bleiben dadurch informationshalber im System verfügbar.
+
+Implementiert ist der _Ex-Partner_ als eine besondere Form der [Relation](#Relation)
+der Person des Ex-Partner (_Holder_) zum neuen Partner (_Anchor_) dargestellt.
+Dieses kann zu einer Kettenbildung führen.
+
+
+#### Representative-Contact (ehemals _contractual_)
+
+Ein _Representative_ ist eine natürliche Person, die für eine nicht-natürliche Person vertretungsberechtigt ist.
+
+Implementiert ist der _Representative_ als eine besondere Form der [Relation](#Relation) 
+der Person des Repräsentanten (_Holder_) zur repräsentierten Person (_Anchor_) dargestellt.
+
+
+### VIP-Contact
+
+Ein _VIP-Contact_ ist eine natürliche Person, die für einen Geschäftspartner eine wichtige Funktion übernimmt, 
+nicht aber deren offizieller Repräsentant ist. 
+
+Implementiert ist der _VIP-Contact_ als eine besondere Form der [Relation](#Relation)
+der Person des VIP-Contact (_Holder_) zur repräsentierten Person (_Anchor_) dargestellt.
+
+
+### Operations-Contact
+
+Ein _Operations-_Contact_ ist_ eine natürliche Person, die für einen Geschäftspartner technischer Ansprechpartner ist
+
+Implementiert ist der _Operations-Contact_ als eine besondere Form der [Relation](#Relation)
+der Person des _Operations-Contact_ (_Holder_) zur repräsentierten Person (_Anchor_) dargestellt.
+
+
+### Subscriber-Contact
+
+Ein _Subscriber-_Contact_ ist_ eine natürliche Person, die für einen Geschäftspartner eine bestimmte Mailingliste abonniert.
+
+Implementiert ist der _Subscriber-Contact_ als eine besondere Form der [Relation](#Relation)
+der Person des _Subscriber-Contact_ (_Holder_) zur repräsentierten Person (_Anchor_) dargestellt.
+Zusätzlich wird diese Relation mit dem Kurznamen der abonnierten Mailingliste markiert.  
+
+
+#### Anchor / Relation-Anchor
+
+siehe [Relation](#Relation)
+
+
+#### Holder / Relation-Holder
+
+siehe [Relation](#Relation)
+
+
+#### API
+
+Und API (Application-Programming-Interface) verstehen wir eine über HTTPS angesprochene programmatisch bedienbare Schnittstell 
+zur Funktionalität des hsAdmin-NG-Systems.
