1. OASIS TAX XML TASC Priorities
May 23, 2003

2. Observations
Need to get the third parties to present at the next face to face meeting
Authentication is important but is outside of scope
We know an overall schema won’t work
Need a layer of common infrastructure that tax applications need to take advantage of

3. Goal The goal of TASC is to Identify and share:
The high-level business process models for the different domains (direct, indirect, peripheral activities and G2G)
Best practices and lessons learned
Work already underway - pilots between different jurisdictions and vendors
Common standards, recommendations, specifications and guidelines
Influences that impact the interfaces between tax authorities and third-party applications
Development tools and their direction
Underlying architectural components
