A persisted record of a tool invocation, capturing the input arguments, output, and the conversation it occurred in. Identified by (conversation_id, tool_call_id). Citations in flow documents resolve to these.
JSON-serialized input arguments to the tool.
A curated group of documents sharing a common source or topic. Collections form a shallow hierarchy with one level of nesting.
Stable URI for this column's concept. A column whose convention has an established public-ontology term resolves to that external URI (e.g., cheminf:CHEMINF_000446 for cas_number); a convention without one resolves to a ToxIndex-minted vocabulary term; a column with no convention resolves to a term minted under the owning brick's instance namespace, scoped to that brick, table, and column.
A curated reference dataset, such as a regulatory list, a chemical property table, or a biological endpoint dataset. Each brick contains one or more typed tables with column-level vocabulary annotations.
A node in a flow document tree. Sections are the structural building block: each has an identity, a kind (object, list, scalar, enum), a status, and optional citations linking its value back to tool calls. Workflow schemas define what sections exist; the ontology defines the shape they all share.
Structural type of a document section node.
Identifier of a specific tool invocation within a conversation.
Column names forming the table's primary key.
A column in a brick table. Carries a vocabulary annotation that resolves the column to a stable concept URI: a column whose annotation matches a known controlled-vocabulary convention resolves to a well-known chemical or biological term (e.g., CAS Registry Number, SMILES, InChIKey), and a column with no matching convention resolves to a term minted under the owning brick's instance namespace, scoped to that brick, table, and column.
An indexed document in the platform's regulatory and scientific corpus. Sourced by a crawler, optionally grouped into collections.
An instance of a workflow execution. A structured, schema-conformant document being filled out (or completed) with provenance citations linking each section back to the tool call that produced it.
A repeatable structured process that produces a document, such as a regulatory assessment or a technical evaluation report. Workflows define a schema that guides structured content generation with cited evidence.
Available output formats (e.g., html, pdf, json).
A multi-turn question-and-answer session with the platform's agent.
Canonical source URL for a dataset or tool.
A provenance link from a document section to the tool invocation that produced or supported its value.
A single table within a brick. Contains typed, described columns with optional mappings to external ontology terms.
Classification labels (e.g., epa, echa).
Guidance on how to use this collection for retrieval.
A computational capability available on the platform, such as a QSAR model, a descriptor calculator, or a metabolite predictor. Tools accept structured input (typically a SMILES string) and return structured output.
Provenance links from this section to the tool calls that produced its value.
The tool invocation that produced this section's value.
Structured object with named child fields.
Scientific domain (e.g., Toxicology, Genomics).
Number of sections currently being worked on.
Dot-delimited path to a node in a flow document tree.
Parent collection (one level of nesting).
The root-level sections of this flow's document tree.
Whether the tool invocation resulted in an error.
JSON Schema defining the tool's accepted input.
Controlled-vocabulary annotation a brick column carries (e.g., CAS, SMILES, InChIKey). Backed by a stable convention that determines how vocab_uri resolves.
User-facing domain ontology for ToxIndex. Defines the concepts that customers and integrations consume: curated reference data, document corpora, computational tools, structured workflows, and their provenance.
The workflow this flow is an instance of.
Identifier of the harvester that sourced a document.
Total number of sections in the document.
