Why this plugin
<ul>
<li>One viewer for WordPress and WooCommerce that is independent of provider.</li>

<li>Uses only the JSON you supply and renders it locally in the browser.</li>
</ul>
<h3>Usage</h3>
<ul>
<li>
Quick start:
<ol>
<li>Edit any post, page, or WooCommerce product and find the “Digital Product Passport” meta box.</li>
<li>Paste valid JSON and update/publish. The plugin stores it as post meta.</li>
<li>Insert the viewer where you want it to appear using either the shortcode or the block below.</li>
</ol>
</li>
<li>
Shortcode: <code>[digital_product_passport]</code>
<ul>
<li>By default renders the JSON saved in the meta box for that post/product.</li>
<li>You can also pass inline JSON via the <code>json</code> attribute (single quotes recommended around the JSON):</li>
<li>Example: <code>[digital_product_passport json='{"id":"urn:uuid:123","type":"Product","name":"Sample"}']</code></li>
<li>Attributes:</li>
<li><code>json</code>: Inline JSON to render (optional). If omitted, uses the saved post meta JSON.</li>
<li><code>view</code>: <code>html|json</code> to pick the default tab (default <code>html</code>).</li>
<li><code>show_raw</code>: <code>true|false</code> to force JSON (deprecated; overrides <code>view</code>).</li>
<li><code>title</code>: Optional title displayed above the viewer.</li>
<li><code>limit</code>: Number of top-level sections to show before a Show more toggle. <code>0</code> (default) shows all.</li>
<li><code>include</code>: Comma-separated list of section keys/labels to include (case-insensitive; matches raw keys or humanized labels). Example: <code>include="id,type,manufacturer"</code>.</li>
<li><code>exclude</code>: Comma-separated list of section keys/labels to hide. Example: <code>exclude="identifiers,documentation"</code>.</li>
<li><code>order</code>: Comma-separated preferred order of sections. Items not listed keep their natural order after these. Example: <code>order="id,type,manufacturers,identifiers"</code>.</li>
<li>
<code>more_label</code> / <code>less_label</code>: Override the Show more/Show less button text.
</li>
<li>
Examples:
</li>
<li><code>[digital_product_passport view="html" title="Digital Product Passport"]</code></li>
<li><code>[digital_product_passport view="json"]</code></li>
<li><code>[digital_product_passport limit="5" order="ID,Type,Manufacturers" exclude="Documentation"]</code></li>
<li><code>[digital_product_passport include="ID,Version,Language,Identifiers" more_label="Show all details" less_label="Show fewer"]</code></li>
<li>Note: The legacy <code>[dpp]</code> shortcode has been removed to comply with wp.org prefixing guidelines. Use <code>[digital_product_passport]</code>.</li>
</ul>
</li>
<li>
Block (Gutenberg): “Digital Product Passport”
<ul>
<li>Add the block and (optionally) paste JSON in the block settings to override the post/product meta for that block.</li>
<li>Choose the default tab (HTML or JSON) in the block inspector.</li>
</ul>
</li>
<li>
Classic Editor: Use the “Digital Product Passport” toolbar button
<ul>
<li>Click the button, pick a title and default view (HTML or JSON), then insert. It uses the JSON saved in the meta box.</li>
</ul>
</li>
<li>
WooCommerce: On product edit screens, the same meta box is available. Place the <code>[digital_product_passport]</code> shortcode in any product description area or block to display the viewer on the product page.
</li>
<li>
Viewer controls (front end):
<ul>
<li>Tabs switch between HTML and JSON. The JSON view has a “Copy JSON” button.</li>
<li>Large passports show a Show more/less toggle when <code>limit</code> is set.</li>
</ul>
</li>
<li>
Troubleshooting:
<ul>
<li>If you see “No Digital Product Passport JSON found.”, either save valid JSON in the meta box or pass JSON via the shortcode <code>json</code> attribute.</li>
<li>Ensure the shortcode <code>[digital_product_passport]</code> is present where you expect the viewer to appear.</li>
</ul>
</li>
</ul>
<h3>Compliance and Privacy</h3>
<ul>
<li>Privacy by design: No tracking, no external calls, no cookies.</li>
<li>Data handling: DPP JSON is stored as post meta and rendered client-side. Nothing is sent to third parties.</li>
<li>Security: Output is escaped and JSON is normalized server-side before embedding.</li>
<li>Accessibility: Semantic HTML with ARIA, keyboard navigation, and visible focus.</li>
<li>Performance: Minimal CSS/JS loaded only when the viewer is present.</li>
</ul>
<h3>External services</h3>
<ul>
<li>None required: This plugin does not connect to, depend on, or transmit data to any third‑party/external service. No data leaves your site when rendering a passport.</li>
<li>Example placeholders: The sample JSON shown in the editor includes illustrative links such as <code>https://example.com</code> and <code>https://example.com/manual.pdf</code>. These are placeholders for demonstration only; the plugin does not fetch or otherwise contact those URLs. Replace them with your own documentation links as needed.</li>
<li>Namespaces in SVG: The editor/block icon contains inline SVG markup that references the XML namespace <code>http://www.w3.org/2000/svg</code>. This is a namespace identifier, not a network request or external service.</li>
</ul>
No third‑party terms of service or privacy policies apply because the plugin does not use any external services.
<h3>GDPR and EU Privacy Notes</h3>
<ul>
<li>Personal data scope: This plugin does not collect, track, or profile users. It only renders the DPP JSON you provide. If your JSON contains personal data (for example, a contact person’s name or email), you are the controller of that data.</li>
<li>Lawful basis: Ensure you have a lawful basis under GDPR to publish any personal data included in the DPP. Prefer business contacts or shared inboxes over named individuals where possible.</li>
<li>Data minimization: Avoid including personal data unless strictly necessary for the product passport. Consider using role-based contacts (e.g., support@example.com).</li>
<li>Data location and transfers: The plugin does not perform network requests or transfer data to third countries. Any links inside your JSON are rendered as links only; the plugin does not fetch or proxy them.</li>
<li>Retention: DPP JSON is stored as post meta and retained until you edit or delete the post/product or remove the meta.</li>
<li>Data subject rights (DSR): The plugin does not store visitor-level personal data, so it does not add custom exporters or erasers. If you include personal data in DPP JSON, handle DSRs by updating/removing the JSON in your content.</li>
<li>Privacy Policy helper: The plugin registers guidance for Tools > Privacy so you can include accurate information on your site’s Privacy Policy page.</li>
<li>Redaction hooks: Developers can filter or redact fields before display using the <code>digital_product_passport_viewer_data</code> filter.</li>
<li>Access control: The viewer displays wherever the post/product is visible. Use WordPress visibility/roles or your membership tools to restrict access if needed.</li>
<li>Disclaimer: This is not legal advice. Consult your legal counsel to confirm compliance for your use case.</li>
</ul>

Digital Product Passport

Lightweight, vendor-agnostic Digital Product Passport viewer for WordPress and WooCommerce. Renders DPP JSON as accessible HTML and JSON tabs.

DPPBuilder creates Digital Product Passports for your WooCommerce products, designed to help with EU Digital Product Passport requirements and providing comprehensive product traceability. The JSON output includes Schema.org Product markup and the UN/CEFACT UNTP DPP context to facilitate early interoperability. 
This plugin is fully functional and unlimited. No subscriptions, API keys, or external services are required.
Disclaimer: The official EU Digital Product Passport (DPP) regulation and its JSON data format have not been finalized at the time of this plugin’s release. This plugin is intended for early adopters and developers who want to begin practicing and preparing for DPP implementation in WooCommerce. It uses the closest publicly available draft — the UN/CEFACT UN/Transport & Logistics Programme (UNTP) DPP v0.6.1 pre-release — and follows current best practices for early interoperability. Once the official specification is published, DPPBuilder will be updated to reflect it.

<ul>
<li>One‑Click Passport Generation – From the WooCommerce product editor, generate a JSON Digital Product Passport on demand</li>
<li>Human‑Readable Product Page + QR Code – Create a product DPP page and a QR PNG that links to it; add the QR anywhere in your store</li>
<li>REST API Access – Opt-in public endpoint (disabled by default) to fetch passport data: <code>/wp-json/dppbuilder/v1/passport/{product_id}</code></li>
<li>Manufacturers Directory – Add/search manufacturers, set logos and locations, and display country flags; associate with products</li>
<li>Materials & Compositions – Create custom materials, search and relate them to products for transparent composition data</li>
<li>Comprehensive Product Data – Support for GTIN, manufacturing details, batches, origin, warranty and more</li>
<li>JSON‑LD (Product) Output – Optional schema output to enhance SEO with structured data</li>
<li>UN/CEFACT UNTP Alignment – Includes UNTP DPP JSON-LD context and <code>conformsTo</code> metadata (v0.6.1 pre-release) for closest-available alignment</li>
<li>No External Services – Works entirely within your site; no accounts, no external APIs required</li>
<li>WooCommerce Ready – Compatible with modern Woo features (including HPOS)</li>
</ul>
