ListenLog Meeting Notes

Below are meeting notes and ongoing issues and action item lists. For a detailed description of ListenLog, visit the main ListenLog page.

1/12

Parking Lot

• Where is data stored (by default)? Does it sync to a local store or just stream out?
• Is there any concern from collaboration stations and partners that there's no exclusive access to data / analytics?
• What data do we capture? Application behavior data in addition to basic listen data? What about rating data? Location data?
  • Should the standard by minimal for extensibility vs. maximal for enhanced value/functionality
  • Privacy concerns (EFF Chair Brad Templeton)
• Security / encryption on the stored data? Which bits?
• How best to communicate and promote the ListenLog concept and where the key benefits and differentiators are? How do we address naysayers and differentiate from alternative approaches, e.g. APML?
• How do we do identity? How do we make it swappable? Do we use icards, openID, Oauth?
• How do we start the service without identity? (e.g. access to device ID?)
• Do users have control over what's stored?
• What's the absolute minimum of device-side functionality?
  • Opt-out(?)
  • Change repository
  • Assign identity
• Where does legal and TOS come in? (see rights and contracts below)
• Does anyone enforce standards compliance?
• Who does the work / coding?
  • PRX + who?
• Do we think about revenue / sustainability? PRX has two roles here - one to build codebase and standards for storage, the other to think about services and how we'd use the data.
• Do we do opt out for data capture? (probably yes)
• Do we provide "public by default," e.g. ubiquitious, anonymous access to the data out of the box (probably no)
• Can we open source iphone bit? Publicly available libraries?
• What's in the first release?
  • Should we provide ability for users to release data? How and to whom? What capacity for sharing? What terms? Anon vs. nonanon?
• Does there need to be database legal protection underlying data rights access to drive user terms?

/13

• How do we make the data inherently more anonymous?
  • Match account data between logs
  • Make timestamp and LAT-LONG fuzzy?
• What data rights can a user authorize for third parties?
  • propagation rights (the grantee can't extend to someone else)
  • public rights vs. directed/granted rights (e.g. for anyone to use vs. for specific entity to use)
    • anon/non-anonymous
    • Most rights issues/rats nests are associated with granted rights
  • How long you can use the data for? Keep the data?
  • Rights to cease use, remove data(?) + confirmation(?)
  • Can't use this to try and find/identify someone - reverse-engineering rights
  • commercial/non-commercial?
  • Contact me (e.g. DNC)
  • Compare to IRB
• Contract rights
  • Investigate proactively - what is it that pandora might want to do? What is reasonable?
    • give me audio recommendations
    • use for product development
  • Don't cross-correlate/aggregate (e.g. social network correlation, Ben Laurie) - piercing identity/privacy data
  • Endorsement / assignment to my identity

Core Requirements

• what data is going to be captured
• where is it stored and in what format
• how does one identify oneself / assign identity
• what's the minimum functionality that needs to live on the device
• what's the minimum functionality that needs to live remotely
• additional / core functionality to prove value necessary?
• Determine protections for communication and storage between client app and repository authenticated, encrypted, etc.

Action Items

• Draft functional requirements
• Doc talk to Berkman legal re: user rights / terms

1/20

• There is a core set of things to figure out to proceed with this project. We'll focus on those:
  • What data will we capture?
  • What format will we send and store the data in?
  • How is this data being transmitted and stored?
  • How do we maintain integrity, privacy, and provide the required minimum of user control (e.g. "delete my data")?
  • How do we assign or associate identity?

• In discussing data capture, Keith argued for being minimal and conservative and providing a mechanism for extending
• Agreement that our proposed data, format, and services will deal with listening attention data only; both for on-demand (file) audio as well as streaming audio
• Open question about whether Sound Exchange / RIAA requires specific formats, if so, might be nice to comply
• XRI be resolved / discoverability

• XDI can be used to transmit and/or store; X3 looks promising
• XRI = identifier - resolvable to an XDI endpoint
• XDI dictionary - like an XML schema
• XRI authority resolution server (open XRI)
• community iname registry
• inumber (this is how you handle reassignment)
• At what level will we register?
• How will we maintain this registry?
• How will other applications that write to LL handle XRI? Will they resolve to their own server?
• What about dupes?
  • xri synonyms is the answer?
• Use iname registration for digital identity?
  • might not need an icard selector on the iphone
  • Simpler way?

Action Items

• Diagram high-level architecture
• Prep for discussing identity options next week
• Look into Sound Exchange reporting formats and PBcore formats

2/26

Action Items

• Make some design decisions to get us started with POC development
• Create a boxes and arrows diagram to help represent the data sets and functional entities and where they live
• Have a convo with berkman RE: servers and hosting the user data
• Identity + claimant - how best to handle user identity (focus on near-term)?
• XDI dictionary - designing what info is sent to log, registrants, etc.
• Revisit user functionality on wiki - what do we really need to do? What role should XRI/XDI (and existing OpenXRI code) do for us here?
