TravelFeed v1

[tiotdev]

The following modifications were made to Hivemind to create a customised instance fit for the needs of TravelFeed:

hive_posts_cache:

• Valid posts with a minimum word count of 250 words and travelfeed in the tags and/or category are marked with true in the new column is_travelfeed. Defaults to false.

• Add columns for latitude and longitude, osm_type and osm_id. At a later release, these will be extracted from the post's json_metadata. In the current version, nothing is extracted from the json_metadata since the specification of how the information will be stored is work in progress. Instead the post body is scanned for a SteemitWorldMap code snippet (swmregex), osm_type and osm_id are obtained from Nominatim (see below). Default to NULL.

• Add PostGIS to the database and a column for geo_location. This enables better location queries.

• Add columns for osm_type, osm_id, country_code, subdivision, city, and suburb, all provided by Nominatim using geopy. Default to NULL.

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

• Modified column total_votes to show the "travelfeed miles", each vote is counted by its percentage (0-10)

hive_accounts:

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

Calls from the API to the Hivemind database will 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;
• Get a list of sublocations (e.g. cities in subdivision)
