Roadmap 1. Open 2. Accessibility 3. Next Steps
Open data is good.
“data is open if anyone is free to use, reuse,
and redistribute it ...”
“subject to the requirement to attribute and/or share-alike” - Open
Knowledge Definition
- open license - open format - available for download
Access
assumptions 3
There are different types of open data users.
Different users have different needs and abilities.
Data accessibility matters.
users 3
casual
casual • least technical • dataset discovery • basic needs:
ability to query and download
casual • geoportal • simple html table • solid metadata
• intuitive interface
mmatic progra
programmatic • Tech skills/API familiarity • spatial query • download
sub-section of larger dataset based on parent process
programmatic • API • developer documentation • solid metadata •
interface optional
bulk
bulk • Need entire datasets, not spatial intersections • Data
APIs/manual retrieval workflows do not scale • Sometimes retrieve data via physical drives
bulk • interface optional • FTP-like access • reasonable bandwidth
for download retrieval
next steps
Open data users change as tech changes.
Access should be a policy and tech consideration.
