storageContext + Nextcloud
Unlock organizational knowledge from Nextcloud files, documents, and collaborative workspaces into your enterprise knowledge graph
OVERVIEW
Nextcloud is the most widely deployed open-source file sync and collaboration platform for organizations that require complete data sovereignty. Used by the German Federal Government, the French Ministry of Education, and thousands of enterprises worldwide, Nextcloud provides file storage, document collaboration, calendaring, project management, and communication capabilities -- all running entirely on the organization's own infrastructure. For defense contractors, government agencies, and regulated enterprises, Nextcloud's on-premise architecture eliminates the data sovereignty concerns that prevent adoption of cloud-based alternatives like Google Drive, Dropbox, or OneDrive.
Over years of operation, Nextcloud instances accumulate enormous volumes of organizational knowledge in documents, spreadsheets, presentations, PDFs, and shared files. Project proposals are drafted in Nextcloud Office, technical specifications are stored in shared folders, compliance evidence is organized in group directories, and meeting notes are collaboratively edited in real time. But finding the right document across thousands of folders and shares is increasingly difficult as the content volume grows. Nextcloud's built-in full-text search helps with keyword matching, but it cannot connect a document to the Jira ticket that requested it, the Mattermost discussion that shaped its content, or the GitLab repository it documents.
Context connects to your Nextcloud instance and incorporates file content, metadata, sharing relationships, and collaborative document history into your enterprise knowledge graph. When a program manager asks "where is the latest system architecture document for the radar subsystem?", Context does not just find the document -- it surfaces the Nextcloud file along with the Mattermost channel where the architecture was discussed, the Jira epic tracking the radar subsystem development, and the GitLab repository containing the implementation. All processing runs entirely on your infrastructure with zero data exfiltration, maintaining the data sovereignty guarantee that led you to choose Nextcloud in the first place.
KEY CAPABILITIES
Key Capabilities
- 01File content extraction and indexing -- parse and index documents, spreadsheets, presentations, PDFs, and text files stored in Nextcloud with full-text search across all supported formats
- 02Folder and share structure mapping -- understand your Nextcloud organizational hierarchy including group folders, external storage, and sharing relationships between users and groups
- 03Collaborative document history -- track changes in Nextcloud Office documents, connecting edits to the people who made them and the organizational context that triggered updates
- 04Tag and metadata indexing -- extract Nextcloud's file tags, comments, and custom metadata to enhance knowledge graph relationships and search relevance
- 05Cross-tool document linking -- automatically connect Nextcloud files to related Jira tickets, Mattermost discussions, GitLab repositories, and Redmine issues that reference them
- 06Permission-aware indexing -- respect Nextcloud's file sharing permissions, group folder access controls, and external storage mount points so that restricted files are only visible to authorized users
USE CASES
Use Cases
Government Document Discovery
A government agency stores thousands of policy documents, technical reports, and compliance artifacts in Nextcloud. Finding the right document across nested folder hierarchies and group shares is a daily challenge. Context indexes the entire Nextcloud file structure and connects documents to the organizational context in which they were created -- the Redmine issues that requested them, the Mattermost discussions that shaped their content, and the MediaWiki articles that reference them. Staff ask natural language questions and receive citation-backed answers that identify the exact Nextcloud file and its surrounding context.
Defense Program Evidence Management
A defense contractor uses Nextcloud to store compliance evidence, test reports, and design documents for multiple programs. During audits, assembling the complete evidence package for a specific control requires searching across dozens of folders and shares. Context links Nextcloud files to the Redmine issues tracking compliance requirements, the GitLab test results verifying controls, and the Mattermost discussions documenting review decisions. Audit evidence assembly that took days now takes minutes.
Research Data Organization
A research organization uses Nextcloud to share datasets, experimental results, and draft publications. Context connects these files to the project tracking in Redmine, the discussions in Mattermost, and the documentation in Wiki.js. Researchers can search across the full knowledge landscape to find relevant prior work, understand the provenance of datasets, and trace the evolution of research findings from raw data to published results.
Collaborative Document Context Recovery
Teams collaboratively edit documents in Nextcloud Office but the rationale behind specific content decisions is lost once the document is finalized. Context connects document edit history to the Mattermost discussions where content was debated, the Jira tickets that specified requirements, and the meeting calendar events where decisions were made. The full context behind any document section is recoverable through the knowledge graph.

FREQUENTLY ASKED QUESTIONS
Frequently Asked Questions
Does Context work with self-hosted Nextcloud in air-gapped environments?
Yes. Context deploys entirely on your infrastructure with no outbound network dependencies. The Nextcloud connector communicates with your Nextcloud instance over your internal network using the OCS API and WebDAV. No file content or metadata leaves your firewall at any point.
What file types does Context index from Nextcloud?
Context extracts and indexes content from PDF, DOCX, XLSX, PPTX, ODT, ODS, ODP, TXT, Markdown, CSV, and other common document formats. For binary formats like images, Context indexes file metadata including names, tags, comments, and sharing information. You can configure which file types and folder paths to include or exclude.
Does Context respect Nextcloud sharing permissions?
Yes. Context respects Nextcloud's file sharing model including user shares, group shares, group folders, and external storage mount points. When users query Context, they only see results from files their Nextcloud permissions allow them to access. Permission sync runs on a configurable schedule to stay current with access control changes.
How does Context handle Nextcloud group folders?
Context fully supports Nextcloud group folders, which are commonly used in enterprise deployments to manage team-level file storage. Group folder access permissions are mapped to Context's access control system, ensuring that files in group folders are only visible to users who are members of the corresponding Nextcloud groups.
Does Context index Nextcloud Office collaborative documents?
Yes. Context indexes documents edited with Nextcloud Office (Collabora or OnlyOffice integration), including the current content and available version history. Collaborative editing context is connected to the broader knowledge graph, linking documents to the organizational tools and conversations that reference them.
Can Context connect to multiple Nextcloud instances?
Yes. Context supports connecting to multiple Nextcloud instances simultaneously. Knowledge from all instances is unified in a single graph with permissions enforced per-user based on their access in each instance. This is useful for organizations with separate Nextcloud deployments for different departments, classification levels, or geographic regions.
SETUP OVERVIEW
Setup Overview
Install the Context Nextcloud connector using Helm or deploy it on bare metal. Create a Nextcloud service account with read access to the files and folders you want to index. Generate an app password for API authentication. Configure the connector with your Nextcloud instance URL and credentials. For air-gapped deployments, provide internal CA certificates if needed. Context will perform an initial sync of file metadata and content, then poll for changes via the activity API. Indexing speed depends on file volume and document sizes -- most organizations are fully indexed within a few hours.
