Metadata meaning

What does Metadata mean?
Metadata, in legal practice, is the information describing an electronic document’s properties, history and context (for example author, creation and modification dates, recipients, file path, email headers, tracked changes, comments, versions, and EXIF/geolocation). It is embedded in the native file and is often lost or obscured when a document is converted to an electronic image (such as PDF/TIFF) or to paper. In England and Wales, the civil procedure rules recognise metadata: Practice Direction 31B defines it as “data about data”, and Practice Direction 57AD (Disclosure in the Business and Property Courts) requires parties to consider whether relevant metadata should be preserved, searched and produced. Across Scotland, Northern Ireland and Ireland, the term is used descriptively in disclosure/discovery; courts may order production of native files or associated metadata where relevant and proportionate. Practical significance: metadata can be crucial evidence of authenticity, timing, dissemination, version history and document integrity, and can include system and application audit trails. Parties should act early to preserve it (for example suspending auto-deletion), agree formats for disclosure/production (native files or images with load files/fields), and address privilege, redaction and data protection. Requests for metadata should be targeted to relevant fields and justified by proportionality.

CJEU: job site scraping of links and metadata may infringe sui generis database right if it risks recovery of investment (CV‑Online Latvia v Melons, C‑762/19)

‘CV-Online Latvia’ SIA v ‘Melons’ SIA Case C-762/19 What are the practical implications of this case? Across the EU, when a website or online database provides a search tool that automatically draws into its results information sourced from third-party databases, this will typically infringe database right. There can, however, be circumstances where the practice is lawful if it can be shown that using data from those third-party databases does not prejudice the maker’s investment—for instance, where the data is deployed in a wholly unrelated market that the maker neither foresaw nor competes in. Nonetheless, in most situations it will be necessary to obtain permission from the maker of any third-party databases employed to produce an aggregated search result. What was the background? A jobs website (Melons) offered a search engine that queried several websites hosting job advertisements. It compiled hyperlinks from all of these sources (in particular CV-Online)...

Disclosure of Electronic Device Contents: Control, Compulsion, Third-Party Rights, Metadata and Imaging under CPR PD 57AD (England and Wales)

This guidance addresses the collection and examination of electronic devices, raising issues such as identifying who controls a device and, where the controller is not the party to the litigation, whether they can be required to provide it to the litigating party. How data on a device is searched, and how it is assessed for disclosure in the case—versus protection by legal professional privilege or another exception—is vital. It also considers the rights of third parties in relation to data on such devices. Why devices are potentially important in disclosure In Pipia v BGEO Group Ltd, Mrs Justice Cockerill considered whether a personal mobile phone used by a witness who had been a senior executive at the defendant company should be searched to meet the defendant’s disclosure duties. She concluded that it could be, on the facts—see: Are any devices exempt from searching?—and outlined in her judgment why device contents are regarded as valuable sources of information in disputes, especially in the business context. She stated: ‘I accept...

Electronic disclosure in international arbitration: planning, scope, metadata and technology, with guidance from IBA Rules, CPR PD 57AD/31B, ICC/LCIA/CIArb/ICDR/Prague Rules, and data protection considerations

How electronic disclosure is used in arbitration There is no single mandatory framework governing e-disclosure in arbitration. This aligns with the overarching principle that arbitral procedure remains adaptable, and that the tribunal is empowered to set the evidential rules in each individual case, subject to any agreement between the parties. As electronically stored information (ESI) will typically comprise a large share of the material in many arbitrations, careful planning is required to manage and deploy it throughout the proceedings so that parties can present their cases effectively without the exercise of producing the evidence becoming unduly burdensome. Note: in arbitration the phrase ‘document production’ is more commonly used than ‘disclosure’, although ‘e-disclosure’ is frequently applied in both senses and contexts. Ordinarily, parties in arbitration provide at an early stage the documents on which they rely. The opposing side may then seek any additional documents they wish to inspect, and any disagreement about whether such material should be produced is put before the tribunal for determination and resolution...
