Redesign Semantic Identifier (Strict Format Rules)

[andi-huber]

• [x] Delimiter in SID (parsable) format should be set in stone, rather than allow that to be a parameter (Spec)
• [x] systemId should be lowercase (namespace like) eg. at.gd or de.bls following Java's package name rules https://docs.oracle.com/javase/specs/jls/se6/html/packages.html#7.7
• [x] systemId should allow an optional sem-ver suffix like eg. de.bls/3.02
• [x] objectId should allow an optional context suffix like eg. food, recipe, food.descriptor or recipe.descriptor

globodiet
  system: at.gd
  version: 2.0
  context: food | recipe | food-desc | recipe-desc
  object: 00123

# formats to -> SID[at.gd/2.0:food/00123]

bls
  system: de.bls
  version: 3.02
  context:
  object: F123456

# formats to -> SID[de.bls/3.02:F123456]

In addition there is need for free-text descriptors for brand names say:

brand
  system: global
  version:
  context: brand
  object: zurück zur natur

# formats to -> SID[global:brand/‹zurück zur natur›] ... literal quotation

• [x] broken poc, fco reading
• [x] broken brand mapping (investigate via todo-reporter)
