The Geoscience Knowledgebase is an experimental effort to encode all information and knowledge from the USGS | The Geoscience Knowledgebase is an experimental effort to encode all information and knowledge from the USGS earth systems science portfolio. It is a compelling idea to have domain-specific knowledge graphs sitting online and accessible to anyone that are "adjacent" to Wikidata but separate in that they are maintained by a group with vested interest in building them and using them in practice. As a government science institution, we have our own requirements on how we need to manage our information, and we likely don't want to have us government folks messing about directly in the "Global Knowledge Commons." Rather, our information is donated into the public domain for anyone else to do what they like. Read more about our motivation and background on the project in the [[About]] page. | ||
Below, you will find a description of the main entities we are building here. Each section should have an example query that you can use to explore. This is all work in progress, so you'll see new things coming in as we get them worked out. You'll note some links to discussion pages where we are working through the specifics on how to model and encode our information into the graph. | Below, you will find a description of the main entities we are building here.

Entities are built iteratively over time with software codes used to introduce them to the knowledgebase. We may start an entity representation with only a couple of pieces of information, with the bare minimum being a label, description, and either an "[[Property:P1|instance of]]" or "[[Property:P2|subclass of]]" claim, depending on the purpose of the entity in the knowledgebase. We also describe source material as entities classified as "[[Item:Q26267|knowledgebase source]]." Claims (or statements) made about an entity should always have at least one reference that essentially cites the source for the statement. These will often point to a "knowledgebase source" item or may use "[[Property:P31|reference URL]]" when the reference source is simply a single linkable online resource. Over time, we may revisit the initial starter code that introduced an entity to the knowledgebase to change how it operates and bring in further claims. We may also change the nature of how an entity specifies its source by changing of adding to references. | Entities are built iteratively over time with software codes used to introduce them to the knowledgebase.

It is organized into sections describing a few things about the major entity types. Each section may contain a link to an associated "item talk" page in this Wikibase instance that discusses the evolution of the entity. Each section will also contain a link to the associated ShExC schema for the entity type as those are developed iteratively. Schemas facilitate interactions with the knowledgebase such as ongoing multimodal introduction of new entity instances and claims. | ||
