1. A computer implemented method, comprising:
detecting an input request to create a digital card representing a digital item;
obtaining digital item metadata corresponding to the digital item;
generating the digital card including the digital item metadata, wherein the digital card does not include the digital item;
generating a card output to store the digital card in a data pod in a given digital card data storage system of a plurality of digital card data storage systems in a de-centralized digital card data storage system architecture, each respective digital card data storage system, of the plurality of digital card data storage systems, having one or more data pods storing one or more digital cards, wherein each of the one or more digital cards represents a digital item stored in a digital item data storage system of a plurality of digital item data storage systems having a plurality of types of security control;
detecting a tag input identifying a selected digital card, of a plurality of digital cards stored on the de-centralized digital card data storage system architecture, to tag with a tag;
generating a graph corresponding to the selected digital card, the graph including a tag node representing the tag and a digital card node representing the selected digital card, and a relationship portion identifying that the tag is applied to the selected digital card to obtain a tagged digital card;
exposing an interface to access, through the data pod accessing system based on the graph, a set of digital cards of the plurality of digital cards stored on the de-centralized digital card data storage system architecture, wherein at least some of the set of digital cards are spread out across the decentralized digital card data storage system and are stored on different digital card data storage systems of the plurality of digital card data storage systems
generating a set of projections of the set of digital cards for representing digital items associated with the set of digital cards, and
presenting, via the interface, the set of projections of the set of digital cards spread out across the de-centralized digital card data storage system architecture as if originating from one logical location, wherein the set of projections are generated and presented without interfacing with the security controls of the plurality of digital item data storage systems.
