+
+### *Schema-F* für Permissions, Rollen und Grants
+
+Permissions, Rollen und Grants werden in den INSERT/UPDATE/DELETE-Triggern von Geschäftsobjekten erzeugt und gelöscht. Das Löschen erfolgt meistens automatisch über das zugehörige RbacObject, die INSERT- und UPDATE-Trigger müssen jedoch in *pl/pgsql* ausprogrammiert werden.
+
+Das folgende Schema soll dabei unterstützen, die richtigen Permissions, Rollen und Grants festzulegen.
+
+An einigen Stellen ist vom *Initiator* die Rede. Als *Initiator* gilt derjenige User, der die Operation (INSERT oder UPDATE) durchführt bzw. dessen primary assumed Rol. (TODO: bisher gibt es nur assumed roles, das Konzept einer primary assumed Role müsste noch eingeführt werden, derzeit nehmen wir dafür immer den `globalAdmin()`. Bevor Kunden aber selbst Objekte anlegen können, muss das geklärt sein.)
+
+#### Typ Root: Objekte, welche nur eine Spezialisierung bzw. Zusatzdaten für andere Objekte bereitstellen (z.B. Partner für Relations vom Typ Partner oder Partner Details für Partner)
+
+Objektorientiert gedacht, enthalten solche Objekte die Zusatzdaten einer Subklasse; die Daten im Partner erweitern also eine Relation vom Typ `partner`.
+
+- Dann muss dieses Objekt zeitlich nach dem Objekt erzeugt werden, auf dass es sich bezieht, also z.B. zeitlich nach der Relation.
+- Es werden Delete (\*), Edit und View Permissions für dieses Objekt erzeugt.
+- Es werden **keine** Rollen für dieses Objekt erzeugt.
+- Statt eigener Rollen werden die o.g. Permissions passenden Rollen des Hauptobjekts zugewiesen (granted) bzw. aus denen entfernt (revoked).
+  - Handelt es sich um Zusatzdaten zum Zwecke der Spezialisierung, dann z.B. so: 
+      - Delete (\*) <-- Owner des Hauptobjektes
+      - Edit <-- **Admin** des Hauptobjektes
+      - View <-- Agent des Hauptobjektes
+  - Handelt es sich um Zusatzdaten, für die sich Edit-Rechte delegieren lassen sollen (wie im Falle der Partner-Details eines Partners), dann z.B. so:
+      - Delete (\*) <-- Owner des Hauptobjektes
+      - Edit <-- **Agent** des Hauptobjektes
+      - View <-- Agent des Hauptobjektes
+- Für die Rollenzuordnung zwischen referenzierten Objekten gilt:
+  - Für Objekte vom Typ Root werden die Rollen des zugehörigen Aggregator-Objektes verwendet. 
+  - Gibt es Referenzen auf hierarchisch verbundene Objekte (z.B. Debitor.refundBankAccount) gilt folgende Faustregel:
+        ***Nach oben absteigen, nach unten halten oder aufsteigen.*** An einem fachlich übergeordneten Objekt wird also eine niedrigere Rolle (z.B. Debitor.ADMIN -> Partner.AGENT), einem fachlich untergeordneten Objekt eine gleichwertige Rolle (z.B. Partner.ADMIN -> Debitor.ADMIN) zugewiesen oder sogar aufgestiegen (Debitor.ADMIN -> Package.TENANT).
+  - Für Referenzen zwischen Objekten, die nicht hierarchisch zueinander stehen (z.B. Debitor und Bankverbindung), wird auf beiden seiten abgestiegen (also Debitor.ADMIN -> BankAccount.REFERRER und BankAccount.ADMIN -> Debitor.TENANT).
+
+Anmerkung: Der Typ-Begriff *Root* bezieht sich auf die Rolle im fachlichen Datenmodell. Im Bezug auf den Teilgraphen eines fachlichen Kontexts ist dies auch eine Wurzel im Sinne der Graphentheorie. Aber in anderen fachlichen Kontexten können auch diese Objekte von anderen Teilgraphen referenziert werden und werden dann zum inneren Knoten.
+
+
+#### Typ Aggregator: Objekte, welche weitere Objekte zusammenfassen (z.B. Relation fasst zwei Persons und einen Contact zusammen)
+
+Solche Objekte verweisen üblicherweise auf Objekte vom Typ Leaf und werden oft von Objekten des Typs Root referenziert.
+
+- Es werden i.d.R. folgende Rollen für diese Objekte erzeugt:
+    - Owner, Admin, Agent, Tenent(, Guest?)
+- Es werden Delete (\*), Edit und View Permissions für dieses Objekt erzeugt.
+- Die Permissions werden den Rollen sinnvoll zugewiesen, z.B.:
+    - Owner -> Delete (\*)
+    - Admin --> Edit
+    - Tenant (oder ggf. Guest) --> View
+-  Außerdem werden folgende Grants erstellt bzw. entzogen:
+    - Initiator --> Owner
+    - Owner --> Admin
+    - Admin --> Referrer
+    - Admins der referenzierten Objekte werden Agent des Aggregators
+    - Tenants des Aggregators werden Referrer der referenzierten Objekte
+
+### Typ Leaf: Handelt es sich um ein Objekt, welches (außer zur Modellierung separater Permissions) keine Unterobjekte enthält (z.B. Person, Customer)?
+
+Solche Objekte werden üblicherweise von Objekten des Typs Aggregator, manchmal auch von Objekten des Typs Root, referenziert.
+
+- Es werden i.d.R. folgende Rollen für diese Objekte erzeugt:
+    - Owner, Admin, Referrer
+- Es werden Delete (\*), Edit und View Permissions für dieses Objekt erzeugt.
+- Die Permissions werden den Rollen sinnvoll zugewiesen, z.B.:
+    - Delete (\*) <-- Owner
+    - Edit <-- Admin
+    - View <-- Referrer

+(this is just a scribbled idea, that's why it's still in German)
+
+Ich habe mal wieder vom RBAC-System geträumt 🙈 Ok, im Halbschlaf darüber nachgedacht trifft es wohl besser. Und jetzt frage ich mich, ob wir viel zu kompliziert gedacht haben.
+
+Bislang gingen wir ja davon aus, dass, wenn komplexe Entitäten (z.B. Partner) erzeugt werden, wir wir über den INSERT-Trigger den Rollen der verknüpften Entitäten (z.B. den Rollen der Personendaten des Partners) auch Rechte an den komplexeren Entitäten und umgekehrt geben müssen.
+
+Da die komplexen Entitäten nur mit gewissen verbundenen Entitäten überhaupt sinnvoll nutzbar sind und diese daher über INNSER JOINs mitladen, könnte sonst auch nur jemand diese Entitäten, der auch die SELECT-Permission an den verküpften Entitäten hat.
+
+Vor einigen Wochen hatten wir schon einmal darüber geredet, ob wir dieses Geflecht wirklich komplett durchplanen müssen, also über mehrere Stufen hinweg, oder ob sehr warscheinlich eh dieselben Leuten an den weiter entfernten Entitäten die nötien Rechte haben, weil dahinter dieselben User stehen. Also z.B. dass gewährleistet ist, dass jemand mit ADMIN-Recht an den Personendaten des Partners auch bis in die SEPA-Mandate eines Debitors hineinsehen kann.
+
+Und nun gehe ich noch einen Schritt weiter: Könnte es nicht auch andersherum sein? Also wenn jemand z.B. SELECT-Recht am Partner hat, dass wir davon ausgehen können, dass derjenige auch die Partner-Personen- und Kontaktdaten sehen darf, und zwar implizit durch seine Partner-SELECT-Permission und ohne dass er explizit Rollen für diese Partner-Personen oder Kontaktdaten inne hat?
+
+Im Halbschlaf kam mir nur die Idee, warum wir nicht einfach die komplexen JPA-Entitäten zwar auf die restricted View setzen, wie bisher, aber für die verknüpften Entitäten auf die direkten (bisher "Raw..." genannt) Entitäten gehen. Dann könnte jemand mit einer Rolle, welche die SELECT-Permission auf die komplexe JPA-Entität (z.B.) Partner inne hat, auch die dazugehörige Relation(ship) ["Relation" wurde vor kurzem auf kurz "Relation" umbenannt] und die wiederum dazu gehörigen Personen- und Kontaktdaten lesen, ohne dass in einem INSERT- und UPDATE-Trigger der Partner-Entität die ganzen Grants mit den verknüpften Entäten aufgebaut und aktualisiert werden müssen.
+
+Beim Debitor ist das nämlich selbst mit Generator die Hölle, zumal eben auch Querverbindungen gegranted werden müssen, z.B. von der Debitor-Person zum Sema-Mandat - jedenfalls wenn man nicht Gefahr laufen wollte, dass jemand mit Admin-Rechten an der Partner-Person (also z.B. ein Repräsentant des Partners) die Sepa-Mandate der Debitoren gar nicht mehr sehen kann. Natürlich bräuchte man immer noch die Agent-Rolle am Partner und Debitor (evtl. repräsentiert durch die jeweils zugehörigen Relation - falls dieser Trick überhaupt noch nötig wäre), sowie ein Grant vom Partner-Agent auf den Debitor-Agent und vom Debitor-Agent auf die Sepa-Mandate-Admins, aber eben ohne filigran die ganzen Neben-Entäten (Personen- und Kontaktdaten von Partner und Debitor sowie Bank-Account) in jedem Trigger berücksichtigen zu müssen. Beim Refund-Bank-Account sogar besonders ätzend, weil der optional ist und dadurch zig "if ...refundBankAccountUuid is not null then ..." im Code enstehen (wenn der auch generiert ist).
+
+Mit anderen Worten, um als Repräsentant eines Geschäftspartners auf den Bank-Account der Sepa-Mandate sehen zu dürfen, wird derzeut folgende Grant-Kette durchlaufen (bzw. eben noch nicht, weil es noch nicht funktioniert):
+
+User -> Partner-Holder-Person:ADMIN -> Partner-Relation:AGENT -> Debitor-Relation:AGENT -> Sepa-Mandat:ADMIN -> BankAccount:ADMIN -> BankAccount:SELECT
+
+Daraus würde:
+
+User -> Partner-Relation:AGENT -> Debitor-Relation:AGENT -> Sepa-Mandat:ADMIN -> Sepa-Mandat:SELECT*
+
+(*mit JOIN auf RawBankAccount, also implizitem Leserecht)
+
+Das klingt zunächst nach nur einer marginalen Vereinfachung, die eigentlich Vereinfachung liegt aber im Erzeugen der Grants in den Triggern, denn da sind zudem noch Partner-Anchor-Person, Debitor-Holder- und Anchor-Person, Partner- und Debitor-Contact sowie der RefundBankAccount zu berücksichtigen. Und genau diese Grants würden großteils wegfallen, und durch implizite Persmissions über die JOINs auf die Raw-Tables ersetzt werden. Den refundBankAccound müssten wir dann, analog zu den Sepa-Mandataten, umgedreht modellieren, da den sonst
+
+Man könnte das Ganze auch als "Entwicklung der Rechtestruktur für Hosting-Entitäten auf der obersten Ebene" (Manged Webspace, Managed Server, Cloud Server etc.) sehen, denn die hängen alle unter dem Mega-komplexen Debitor.
