+OpenDevIndex explored a source-backed, structured knowledge map for software, systems, hardware, AI, security, networking, standards and related technology. The existing knowledge modules and Git history are preserved for reference, but **no further feature development or routine content maintenance is planned**. ---- +This repository may later be made private or removed after the portfolio cleanup is complete. -## More than a list of links +## Why development ended -OpenDevIndex is built to answer the question that ordinary directories usually stop before: +A continuously expanding technical knowledge base creates permanent editorial, verification and source-maintenance work. BLCCoreStudio is concentrating on a smaller set of software projects that can be maintained deeply rather than sustaining an indefinitely growing content surface. -> **What is this technology, how does it actually work, what belongs around it, what are the trade-offs, and what should I learn next?** +## Historical source -Each subject is an independently maintained **knowledge module** with structured metadata, authoritative sources, taxonomy, verification history, and—where useful—typed relationships to other technologies. +Previous modules, taxonomy, documentation and development history remain available through the Git history. -A module can grow from a concise source-backed overview into a full technical deep dive without changing its stable address. - -## Start exploring - -The generated [`INDEX.md`](INDEX.md) is the main directory. It groups modules by what they are and shows the domains they belong to. - -A few examples: - -- **[Git](https://github.com/BLCCoreStudio/OpenDevIndex/tree/tool/git/entry)** — flagship deep dive into Git's object model, index, refs, branching, merging, rebasing, packfiles, protocols, performance, recovery, and security boundaries. -- **[Git LFS](https://github.com/BLCCoreStudio/OpenDevIndex/tree/tool/git-lfs/entry)** — large-file workflows around Git. -- **[Docker](https://github.com/BLCCoreStudio/OpenDevIndex/tree/tool/docker/entry)** — container development and packaging workflows. -- **[PyTorch](https://github.com/BLCCoreStudio/OpenDevIndex/tree/framework/pytorch/entry)** — machine-learning framework coverage. -- **[x86-64](https://github.com/BLCCoreStudio/OpenDevIndex/tree/architecture/x86-64/entry)** — computer-architecture coverage using the richer schema-v3 model. -- **[JSON](https://github.com/BLCCoreStudio/OpenDevIndex/tree/format/json/entry)** and **[Apache Parquet](https://github.com/BLCCoreStudio/OpenDevIndex/tree/format/parquet/entry)** — data-format modules mapped into the technology universe. - -The goal is not to produce the longest possible list. The goal is to make every useful click lead somewhere worth reading. - -## What a mature module teaches - -Depending on the subject, a mature OpenDevIndex module can cover: - -- what the technology is and why it exists; -- how it works and what its internal architecture looks like; -- the important concepts, objects, protocols, components, or data structures; -- common workflows, commands, APIs, and practical examples; -- tools and integrations commonly used with it; -- alternatives and meaningful trade-offs; -- performance characteristics and scaling limits; -- reliability concerns and common failure modes; -- security and privacy boundaries; -- common mistakes and operational pitfalls; -- ecosystem and interoperability; -- beginner-to-advanced learning paths; -- authoritative sources and verification date; -- related OpenDevIndex modules and sensible next topics. - -See [`docs/MODULE_STANDARD.md`](docs/MODULE_STANDARD.md) for the full editorial standard. - -## Depth without placeholder content - -OpenDevIndex separates **coverage** from **depth**. - -An overview module can establish a trustworthy node in the map. Important technologies are then progressively upgraded into guides and deep dives. This lets the project broaden its technology coverage without pretending that a one-paragraph entry is a finished learning resource. - -The project deliberately avoids: - -- empty pages created only to increase counts; -- copied marketing descriptions; -- giant command dumps without explanation; -- AI-generated text treated as a source; -- fake rankings or sponsor-driven recommendations; -- graph edges created only to make the graph look denser. - -## A connected technology map - -Technology is easier to understand when subjects are connected rather than isolated. - -Taxonomy v3 separates three ideas: - -1. a **stable module address**, such as `tool/git`; -2. semantic facets such as **kind** and **domains**; -3. typed **relationships** between modules. - -Relationships can express ideas such as: - -```text -depends-on -uses -implements -integrates-with -part-of -alternative-to -based-on -predecessor-of -successor-of -related-to -``` - -This makes it possible to move naturally from a tool to the protocol it implements, the libraries it depends on, alternatives worth comparing, related standards, or the next concept in a learning path. - -## Explore by technology area - -The Technology Universe coverage map keeps growth broad across computing rather than clustering around whatever happens to be easiest to add. - -- [Computer Science Foundations](docs/COVERAGE.md#computer-science-foundations) -- [Programming Languages and Runtimes](docs/COVERAGE.md#programming-languages-and-runtimes) -- [Software Engineering and Architecture](docs/COVERAGE.md#software-engineering-and-architecture) -- [Operating Systems and Systems Software](docs/COVERAGE.md#operating-systems-and-systems-software) -- [Hardware and Computer Architecture](docs/COVERAGE.md#hardware-and-computer-architecture) -- [Networking and Internet Infrastructure](docs/COVERAGE.md#networking-and-internet-infrastructure) -- [Cybersecurity, Cryptography and Privacy](docs/COVERAGE.md#cybersecurity-cryptography-and-privacy) -- [Web Platforms and Development](docs/COVERAGE.md#web-platforms-and-development) -- [Mobile and Desktop Computing](docs/COVERAGE.md#mobile-and-desktop-computing) -- [Databases, Storage and Data Engineering](docs/COVERAGE.md#databases-storage-and-data-engineering) -- [Cloud, DevOps, Infrastructure and SRE](docs/COVERAGE.md#cloud-devops-infrastructure-and-sre) -- [Artificial Intelligence and Machine Learning](docs/COVERAGE.md#artificial-intelligence-and-machine-learning) -- [Graphics, Games, Media and XR](docs/COVERAGE.md#graphics-games-media-and-xr) -- [Embedded Systems, IoT and Robotics](docs/COVERAGE.md#embedded-systems-iot-and-robotics) -- [Open Source Ecosystems](docs/COVERAGE.md#open-source-ecosystems) -- [Standards, Protocols and Formats](docs/COVERAGE.md#standards-protocols-and-formats) -- [Developer Tools and Environments](docs/COVERAGE.md#developer-tools-and-environments) -- [Testing, Debugging and Performance Engineering](docs/COVERAGE.md#testing-debugging-and-performance-engineering) -- [Distributed and Large-Scale Systems](docs/COVERAGE.md#distributed-and-large-scale-systems) -- [Emerging and Historical Technology](docs/COVERAGE.md#emerging-and-historical-technology) - -The coverage model is a planning and quality-control tool—not a public race to inflate repository size. - -## How modules are organized - -Knowledge modules use stable category/slug addresses and live on independently versioned branches: - -```text -tool/git -language/rust -framework/pytorch -protocol/mcp -architecture/x86-64 -format/parquet -concept/virtualization -``` - -A module contains: - -```text -entry/ -├── README.md # human-readable knowledge page -├── entry.yaml # machine-readable metadata -├── sources.md # provenance and authoritative references -└── history.md # verification and editorial history -``` - -Independent module branches let one subject evolve without rewriting the entire index while preserving stable links. - -## Searchable by humans and tools - -OpenDevIndex generates machine-readable search artifacts alongside the public Markdown directory. - -```bash -python scripts/build_index.py --catalog-dir catalog --output-dir dist/index --public-index INDEX.md -python scripts/search_index.py "local ai" --index dist/index/search.json -``` - -Search can use taxonomy-aware fields including kind, domains, tags, deployment type, licensing metadata, and Technology Universe coverage facets. - -The structured model is intended to work for: - -- people browsing on GitHub; -- local search and CLI tools; -- future web interfaces; -- educational and learning-path tools; -- technology comparison views; -- graph exploration; -- other open-source applications that need a reviewed technology catalog. - -## Quality and provenance - -Every published module is expected to be source-backed and independently validatable. - -Core quality controls include: - -- schema validation; -- taxonomy validation; -- source URL safety checks; -- source-health monitoring; -- editorial quality scoring; -- duplicate and category checks; -- Technology Universe coverage validation; -- relationship validation for schema-v3 graph edges; -- pinned third-party GitHub Actions in core workflows. - -Automated checks can validate structure and source reachability. They do **not** replace factual editorial review. - -Primary and authoritative sources are preferred: official documentation, standards, canonical repositories, original research, and security advisories. - -## Publication model - -Reviewed catalogs on trusted `main` drive reproducible module publication. The publisher is idempotent and validation-gated. - -Curated deep-dive modules are protected from accidental automatic replacement, and an older catalog cannot silently downgrade a newer module schema. Intentional replacement requires an explicit override. - -This is important because OpenDevIndex treats hand-curated depth as durable project content rather than disposable generated output. - -## Contributing - -Useful contributions include much more than adding a new technology name. - -You can help by: - -- deepening an existing overview; -- correcting an inaccurate explanation; -- adding authoritative sources; -- documenting architecture or internal concepts; -- improving examples and workflows; -- connecting related technologies with meaningful graph edges; -- documenting alternatives and trade-offs; -- improving security, reliability, or performance coverage; -- proposing a missing technology that fills a real coverage gap. - -See [`CONTRIBUTING.md`](CONTRIBUTING.md) and [`docs/EDITORIAL_POLICY.md`](docs/EDITORIAL_POLICY.md). - -## Project principles - -- **Explain, don't just list.** -- **Prefer primary sources.** -- **Stable links matter.** -- **Depth and coverage are separate quality dimensions.** -- **Relationships should teach something.** -- **Automation should protect curated work, not overwrite it.** -- **No placeholder-content races.** -- **No sponsored rankings.** - -## Documentation - -- [`docs/MODULE_STANDARD.md`](docs/MODULE_STANDARD.md) — module depth and editorial expectations -- [`docs/COVERAGE.md`](docs/COVERAGE.md) — technology-area coverage model -- [`docs/TAXONOMY.md`](docs/TAXONOMY.md) — stable addresses, kinds, domains, and relationships -- [`docs/ARCHITECTURE.md`](docs/ARCHITECTURE.md) — repository and publication architecture -- [`docs/EDITORIAL_POLICY.md`](docs/EDITORIAL_POLICY.md) — quality rules -- [`docs/SEARCH.md`](docs/SEARCH.md) — generated search artifacts -- [`docs/SOURCE_HEALTH.md`](docs/SOURCE_HEALTH.md) — source monitoring -- [`docs/VISION.md`](docs/VISION.md) — long-term scope -- [`ROADMAP.md`](ROADMAP.md) — development direction - -## License - -MIT.
