TravelFeed – Modifying Hivemind

Utopian for TravelFeed:

Utopian.io is running this task request on behalf of the TravelFeed Project.

Repository

https://github.com/travelfeed-io/hivemind

Details:

We need a modified Hivemind instance to power the GraphQL API of our dApp.

The following modifications need to be made to the Hivemind code (Python):

hive_posts_cache:

• Only include posts with a minimum word count of 250 words and travelfeed in the tags and/or category.

• Add columns for latitude and longitude extracted from the post's json_metadata. Here is an example TravelFeed post with a location in the json_metadata.

  • Scan the post body for a SteemitWorldMap code snippet (swmregex) if no (valid) "coordinates" field is set in the json_metadata.
  • If none of the above apply, default value is NULL.

• Add columns for country, subdivision, area, and neighbourhood

  • country (ISO 3166 country code)
  • subdivision (ISO 3166 code for state/province/territory..)
  • area (post code if applicable, otherwise, default to NULL)
  • neighbourhood (for rural areas name of larger region e.g. Black Forest, Outback, Mekong Delta, defaults to NULL if it cannot be determined). All names in English. Use a reverse Geocoding service to obtain these information based on the coordinates. Could be done with GeoPy and Nominatim.

• Add column for curation_score: Percentage of vote by Hive account@travelfeed. Defaults to 0.

hive_accounts:

• Add columns for facebook, instagram, youtube, couchsurfing populated from the json_metadata. Default to NULL.

Components

Calls from the API to the Hivemind database include:

• Location search: Get posts where latitude and longitude is in certain range, possibly sorted by proximity to a given location;
• Text search: Get posts by full text search;
• Feeds: Get posts where author / one or multiple tags / country / subdivision / area / neighbourhood matches/contains request; Get posts chronologically for all authors that are followed by a certain user.
• User search: Get user where location / Steem username / Steem display_name / instagram / facebook / twitter / youtube / couchsurfing ID matches request;
• Order posts by curation score or chronologically.

Deadline

25/3
