Accounts are stored in the neo4j graph, labeled with
user. The account identity is
the email used to sign up (and later verify account). Passwords are hashed with
scrypt @ standard settings (N = 16384, R = 8, P = 1) and transmitted in plain-text.
A project is represented as a graph node with a
project label. Projects are the basic
premise on which collections expand. Each project has a taxonomy.
A collection is represented as a graph node with a
collection label. Collections are the
main and only way of organizing entries and are mainly identified by a combination of their
unique id and non-unique (user provided) name. Each collection has a (potentially nil) set
of taxonomy extensions of the base taxonomy (provided by the project).
An entry is represented as a graph node with a
entry label. Each entry has an additional
entry type label:
challenge. Entry nodes contain the properties specific to
the entry type. They also have relations to their entities. The relationship type is the
taxonomy classification, e.g
Entity / Facet¶
An entity is represented as a graph node with a
facet label and is the free text sample
of at least one entry. The relation type between an
facet determines the
classification of that entity (text sample) for that specific entry. Many entries can
classify the same entity, even with different classifications.
A token is represented as a graph node with a
token label. Tokens are in fact a special
type of authentication nodes. Tokens are given meaning by their relation to the user node.
At the moment only two relation types exist:
RESET_TOKEN for email
verification and password reset, respectively. At the moment tokens don't expire (but they
