Common Roster Language Proposal

[RocketDelivery2]

One of TeamBuilder’s most important long-term goals is to support a common roster language.

The idea is simple:

Any app, website, upload, API, mobile client, legacy system, or external platform should be able to describe a team roster in a shared format that TeamBuilder can understand.

This allows TeamBuilder to become a bridge between systems instead of forcing every team-based workflow into one application.

Why this matters

Team and roster data is often trapped inside separate tools.

A basketball group may use one app.
A gaming group may use another.
A tournament may use a spreadsheet.
A club may use a website.
A legacy system may export text or CSV.
A future mobile app may use its own backend.

TeamBuilder should eventually make those systems interoperable.

First target format

The first target should be JSON because it is widely supported by APIs, web clients, mobile apps, and backend systems.

Future formats may include:

• YAML
• XML
• CSV
• plain text import
• mapped uploads from third-party systems

Early schema concepts

A useful common roster payload will likely need to represent:

• source system information
• team name
• event title
• category
• tags
• status
• date and time
• location
• roster capacity
• current players
• roles
• open spots
• identifiers for synchronization and updates

Design principles

The roster language should be:

• simple
• portable
• documented
• versioned
• API-friendly
• frontend-agnostic
• tolerant of partial data
• useful for many team categories
• designed for imports from other systems

Open questions

1. What fields are required for every roster?
2. What fields should be optional?
3. Should location be exact, approximate, or privacy-protected?
4. How should recurring events be represented?
5. How should skill level or experience be represented?
6. How should open spots and team roles be represented?
7. Should the schema support anonymous or temporary players?
8. How should roster imports handle unknown fields?
9. Should TeamBuilder preserve the original source payload?
10. How should external systems identify updates to the same roster?
