Enum MemoryType

Namespace

LMKit.Agents

Assembly

LM-Kit.NET.dll

Specifies the category of information stored in an AgentMemory data source.

public enum MemoryType

Fields

Semantic = 0

General knowledge and factual information.

Semantic memory stores facts, concepts, and general knowledge that is not tied to a specific personal experience or time. This is the most common type of memory and is used for building knowledge bases, storing product information, domain expertise, and reference material.

Examples:

• "The Earth orbits the Sun in approximately 365.25 days."
• "Our API rate limit is 1000 requests per minute."
• "C# supports both value types and reference types."
• Technical documentation and specifications
• FAQ content and knowledge base articles

This is the default memory type when none is specified.

Episodic = 1

Personal experiences and specific events.

Episodic memory stores information about specific events, experiences, and contextual details that are tied to a particular time or situation. Use this type for conversation history, user-specific interactions, session context, and temporal information.

Examples:

• "On March 15, the user mentioned they prefer detailed explanations."
• "Last session, we discussed migrating from Python to C#."
• "User's birthday is in August; they mentioned it during onboarding."
• Meeting notes and conversation summaries
• User preference observations over time

Episodic memories often include temporal context (dates, times, "last week") and personal pronouns (the user, we, they).

Procedural = 2

Process knowledge and how-to information.

Procedural memory stores information about how to do things: processes, workflows, step-by-step instructions, and methodologies. This type is ideal for runbooks, standard operating procedures, tutorials, and troubleshooting guides.

Examples:

• "To deploy: 1) Run tests, 2) Build release, 3) Push to production."
• "Troubleshooting connection errors: First check network, then verify credentials."
• "Recipe for authentication: Validate token, check permissions, log access."
• Installation guides and setup instructions
• Standard operating procedures (SOPs)

Procedural memories typically contain numbered steps, action verbs (do, run, click, verify), and sequential instructions.

Examples

Example: Organizing memory by type

using LMKit.Agents;
using LMKit.Model;

using var embeddingModel = new LM("path/to/embedding-model.gguf");
var memory = new AgentMemory(embeddingModel);

// Semantic: General knowledge
await memory.SaveInformationAsync(
    dataSourceIdentifier: "product_knowledge",
    text: "Our premium plan includes unlimited API calls and priority support.",
    sectionIdentifier: "premium_features",
    memoryType: MemoryType.Semantic);

// Episodic: User-specific experiences
await memory.SaveInformationAsync(
    dataSourceIdentifier: "user_history",
    text: "On January 15, the user asked about enterprise pricing options.",
    sectionIdentifier: "inquiry_001",
    memoryType: MemoryType.Episodic);

// Procedural: Process knowledge
await memory.SaveInformationAsync(
    dataSourceIdentifier: "procedures",
    text: "To reset a password: 1) Go to Settings, 2) Click Security, 3) Select Reset Password.",
    sectionIdentifier: "password_reset",
    memoryType: MemoryType.Procedural);

// Check memory types
foreach (var ds in memory.DataSources)
{
    var memType = AgentMemory.GetMemoryType(ds);
    Console.WriteLine($"{ds.Identifier}: {memType}");
}

Remarks

MemoryType is modeled after the human cognitive memory system and helps categorize stored information for better organization and potential retrieval optimization. Each data source in AgentMemory is associated with a single memory type.

Memory Type Categories

Type	Purpose and Examples
Semantic	General facts and knowledge: "Paris is the capital of France", "C# is a statically-typed language", product specifications.
Episodic	Personal experiences and specific events: "User mentioned they prefer dark mode", "Meeting with client on March 15", conversation history highlights.
Procedural	How-to knowledge and processes: "Steps to deploy the application", "Recipe for authentication flow", troubleshooting guides.

Usage Notes
A data source can only have one memory type. If you attempt to save information with a different type than the data source was created with, an exception is thrown. Use GetMemoryType(DataSource) to check a data source's type.
