social.arabica.alpha.roaster#

social.arabica.alpha.grinder#

Grinder records with type (hand/electric), burr type (conical/flat), and notes.

social.arabica.alpha.brewer#

Brewing device records with name and description.

social.arabica.alpha.brew#

Brew session records including:

• Bean reference (AT-URI)
• Brewing parameters (temperature, time, water, coffee amounts)
• Grinder and brewer references (optional)
• Grind size, method, tasting notes, rating
• Pours array (embedded, not separate records)

Design Decisions#

References#

All references use AT-URIs pointing to user's own records. Example: at://did:plc:abc123/social.arabica.alpha.bean/3jxy123

Temperature Storage#

Stored as integer in tenths of degrees Celsius. Example: 935 represents 93.5°C

Pours#

Embedded in brew records as an array rather than separate collection.

Required Fields#

Minimal requirements - most fields are optional for flexibility.
