## 3-D Data Acquisition Issues

- Evaluating how to index and process 3-D data for mechanical spares in our data repositories.
- Identify which ISO 10303 STEP Application Protocols (APs) and their Conformance Classes (CCs) will support DoD life cycle business processes for mechanical  parts..
- Develop a Request For Interest (RFI) for OEM, suppliers, and software vendors to provide _certified_ STEP data and viewers that will enable personnel to examine the digital technical data for mechanical AP CCs that are of DoD interest.
- Development of product model Data Item Description (DIDs) for APs chosen for use on contracts.
- Develop test data for ISO 10303 AP 202 products so that software tools can be certified by USPRO for creation, editing and viewing of STEP conforming data.
- MIL-DTL-31000B (Technical Data Packages, General Specification for) update.
- Performance specs for ISO 10303 similar to MIL-PERF 28000B Digital Representation for Communication of Product Data: IGES Application Subsets and IGES Application Protocols
- Develop DFAR contract clause words for acquisition efforts.
- Identify who will create and certify data (ISEA/CFA) for legacy systems.
- Ensure compatibility with future processes (NMCI, Task Force Web, JEDMICS, ICP tools, etc.)
- Incorporate stakeholder input on the viewer requirements into an RFP for site licenses for Inventory Control Point (ICP) users and others.
- Identify demonstration system/parts we can and should acquire 3-D STEP data for.
- Provide tools and training to logisticians to view 3-D data.
- Acquire parts and do cost analysis of savings/quality of 3-D procurement processes.
- How do we buy access to data using web based tools for new systems.
- Digital Signatures
