Data collection is one of the most technically challenging parts of eDiscovery. Once Electronically Stored Information (ESI) is located, it must be extracted in a forensically defensible manner, then placed in a separate repository for review by the legal team. Data collection now requires even more expertise due to the sheer number of devices ESI can be stored on.
Metadata is data about data. It can identify who made a particular document, on what date it was created, and when it was last edited and by whom. When it comes to eDiscovery, metadata is an element that can be easily spoiled, leading to vital evidence becoming unusable or inadmissible. Therefore, copying and pasting a document is an inappropriate strategy for data collection in an eDiscovery project; such an action immediately destroys the authenticity of the metadata.
