hGraph

The typed, bi-temporal knowledge graph within hgres.

About hGraph

hGraph is a typed, bi-temporal knowledge graph. It records when a fact is true and when that fact is known, so changes can be traced across both time axes. It implements SemType’s data model within the hgres stack.

Visit hGraph on hgres.org for the project’s technical documentation.

Logo and icon

The blue gradient “h” is the compact icon. The full hGraph wordmark already includes this symbol as its first letter; use the complete artwork without adding a second icon beside it.

Use the dark lettering on light backgrounds and the light lettering on dark backgrounds. The supplied SVGs retain their detail at any size.

Writing the name

Use hGraph, with a lowercase “h” and a capital “G”. Introduce it as part of hgres when the relationship is not already clear.

Downloads

Use the supplied artwork without redrawing, stretching, or adding effects. Keep enough clear space for the mark to remain legible.

See the Terms of Brand Assets usage for usage guidance.
