An open standard for the structural layer of digital existence.
Status: Draft v0.1.0 — this specification is under active development and is not yet a final standard.
DEL is not SEO. DEL is not GEO. DEL is the structural layer of digital existence that allows websites to be found, understood, trusted, distributed, and operated by humans, search engines, generative AI systems, and autonomous agents.
DEL — Digital Existence Layer — is an open, versioned, evolving specification that defines the minimal structural infrastructure any modern website needs in order to exist meaningfully on today's web. "Existing" on the modern web means being:
- Found — discoverable and crawlable by humans and machines.
- Understood — semantically clear to readers, search engines, and synthetic entities.
- Trusted — carrying minimal, verifiable signals of legitimacy.
- Distributed — shareable with correct previews and metadata across channels.
- Operated — eventually actionable by autonomous agents, not only readable.
DEL does not replace SEO or GEO. SEO optimizes for search ranking. GEO optimizes for generative engine representation. DEL is the structural layer underneath both — the foundation that SEO, GEO, and the agentic web require to function at all.
DEL is organized into six conceptually stable pillars. The pillars themselves are designed to be near-immutable; what evolves over time are the checks, rules, and drivers inside each pillar.
| # | Pillar | Concern |
|---|---|---|
| 1 | Technical Presence | Basic existence and crawl signals: HTTPS, robots.txt, sitemap, canonical, indexability, status codes, crawlability. |
| 2 | Semantic Clarity | The site's ability to clearly express what it is, what it offers, for whom it exists, what problem it solves, and how it is structured. |
| 3 | AI Readability | The ability of a synthetic entity to read, summarize, and correctly represent the site: machine-readable content, structured data, semantic metadata. |
| 4 | Trust Signals | Minimal legitimacy signals: About, Contact, Privacy Policy, Terms, ownership, legal identity, security signals, basic traceability. |
| 5 | Distribution Readiness | Preparedness for correct sharing and distribution: social card metadata, preview images, share titles and descriptions, canonical sharing. |
| 6 | Agentic Readiness | The site's ability to be understood and eventually operated by autonomous agents: clear routes, visible pricing, comprehensible forms, machine-actionable paths. |
The normative definition of each pillar lives in SPEC.md. The machine-readable rule set lives in rules/del-v0.1.json.
| Path | Purpose |
|---|---|
| MANIFESTO.md | Why DEL exists. The central thesis. |
| SPEC.md | The normative specification (Draft v0.1.0). |
| GOVERNANCE.md | How the standard is governed, versioned, and changed. |
| ROADMAP.md | Path from v0.1 draft to v1.0. |
| CHANGELOG.md | Institutional memory: all notable decisions and changes. |
| rfcs/ | Design documents recording foundational and future decisions. |
| rules/ | Machine-readable rule sets, versioned per spec release. |
| examples/ | Worked examples applying DEL to common site archetypes. |
| docs/ | Supporting non-normative documents: glossary, scoring model, agentic occlusion. |
- Site owners and builders who want a structural baseline for digital existence.
- Tool authors building validators, linters, auditors, or CLIs on top of an open rule set.
- Researchers and practitioners working on search, generative engines, and the agentic web.
DEL deliberately speaks about categories of consumers — humans, search engines, generative AI systems, autonomous agents — rather than specific vendors. The standard promises no compatibility with any particular company or product.
DEL Standard is independent and vendor-neutral. Commercial or open-source tools may implement, validate, or extend DEL and describe themselves as "powered by DEL Standard." Existence Compiler, the ecosystem where DEL originated, is expected to be one such implementation — but this repository is the neutral source of truth for the standard, and no implementation has privileged status over the specification.
DEL evolves through an RFC process described in GOVERNANCE.md. During the v0.1 draft phase, issues and discussion are welcome; substantial changes require an RFC.
DEL — Digital Existence Layer was initiated by Hernan Capucci as part of the broader Existence Compiler research and tooling ecosystem, and is maintained as an independent open standard.
The standard is governed by its published specification, rule sets, and RFC process. No individual, company, product, or implementation has privileged status within DEL conformance.
