FOCUS 1.3: Contract Commitments, Split Cost Allocation, and Data Quality

Version 1.3 introduced the first supplemental dataset (Contract Commitments), standardized how providers expose cost-splitting methodology, and added data freshness/completeness metadata.

Release Context

FOCUS v1.3 was ratified by the Steering Committee on December 4, 2025. It’s the most architecturally significant release since v1.0, introducing the concept of supplemental datasets and making the spec’s first foray into exposing cost allocation methodology rather than just allocation results.

Key Features

Contract Commitment Dataset

This is a landmark addition — the first time FOCUS extended beyond the core cost/usage dataset to create a supplemental, linked dataset.

The Contract Commitment dataset isolates contract terms into their own structured records:

  • Start and end dates of the contract
  • Remaining units (how much of the commitment is left)
  • Contract descriptions and terms
  • Commitment type and status

Previously, commitment information was scattered across charge rows — you’d have to reconstruct your commitment portfolio from covering/covered charge relationships. The Contract Commitment dataset provides a single source of truth for all active commitments, their terms, and their remaining obligations.

This pattern (supplemental datasets) is expected to be reused in future versions for other adjacent data domains.

Allocation Columns

FOCUS v1.3 added new columns that let data generators expose how they split costs across workloads. This is a shift from “here’s the allocated cost” to “here’s the allocated cost AND here’s how we calculated it.”

The specification standardizes three allocation methodologies:

  • Resource-based allocation — costs split based on resource ownership/tagging
  • Usage-based allocation — costs split proportional to consumption
  • Hybrid approaches — combinations of the above

Related FOCUS glossary concepts:

  • Allocated Charge — a charge created through allocation operations from an origin charge
  • Allocated Method — the process or formula by which cost is allocated

This transparency is crucial for FinOps teams that need to validate and explain their chargeback numbers. When a business unit questions their allocated costs, practitioners can now point to the methodology, not just the output.

Data Recency and Completeness

v1.3 added metadata columns addressing a persistent trust problem in billing data:

  • Last-updated timestamps — providers must now indicate when a dataset was last refreshed. This tells practitioners whether they’re looking at data from 5 minutes ago or 5 hours ago.
  • Completeness flags — datasets must indicate whether they’re complete (closed billing period) or still being updated (open billing period).

These metadata additions enable:

  • Automated data pipeline quality checks
  • Dashboards that show data freshness
  • Distinction between “this is a preliminary number” and “this is the final number”
  • SLA monitoring for billing data delivery

Architectural Significance

v1.3 establishes two important precedents:

  1. Supplemental datasets are part of FOCUS — the spec is no longer limited to a single cost/usage table. The Contract Commitment dataset proves that related data domains can be standardized alongside the core billing data.

  2. Methodology transparency — FOCUS isn’t just standardizing data values, it’s standardizing the explanation of how data was derived. This raises the bar for what “FOCUS-compliant” means.

Key Points

  • The Contract Commitment dataset is the first supplemental dataset — more are expected in future versions
  • Allocation columns expose the “how” of cost splitting, not just the “what”
  • Data recency/completeness metadata addresses a real trust gap in billing data consumption
  • v1.3 positions FOCUS as increasingly opinionated about data quality, not just data structure
  • The release was accompanied by expanded vendor support for v1.2
