We should figure out a productive way to engage with Data Transfer Project (DTP)

[danbri]

Suggestions for "getting started":

Read the announcements and intro documentation.

• main project web site: https://datatransferproject.dev/
• github repo: data-transfer-project
• Announcements: Facebook, Microsoft, Google, Twitter.
• White Paper
• Data Models area, including readme as overview of general thinking.
• DTP issues: Issue schemaorg/schemaorg#306

Have a look around what's been built so far under models/

Terminology: It seems "data model" in DTP means something like "application/vertical data model" rather than "the relational or JSON or XML or Protobuf data model".

• git clone https://github.com/google/data-transfer-project

• cd data-transfer-project/portability-types-transfer/src/main/java/org/datatransferproject/types/transfer/models

There's a Java codebase, some of it with "per vertical" datamodels indicated via @Json* annotations, for example:

find . -name *.java -exec grep --with-filename @Json {} \;

This gives a feel for what's in there somewhere. A better overview must be possible, but it's a start.

Something not yet mentioned in the Data Transfer Project is the intersection between personal actions and public activities and places that may be marked up in schema.org. For example, I can have my flight info added to my calendar, but can I port that info to another calendar easily? I may want to download details of events I have attended that are on my calendar and keep them. I may also want to keep a list of favorite restaurants, or favorite museums.

As more physical (non-digital) activities become subscription services (like watching movies in theaters), the value of tracking these activities for an individual increases, who may want to monitor their use-value.

There is obvious value in portability of media-focused personal data such as playlists. I think there is also value in events-focused personal data, and schema.org structured data can help bridge this management.
