For example you could lookup a user's profile based on their DID, their Ethereum account, or their Twitter manage; or you could lookup a user's Filecoin account based on their Polkadot account. Check For Updates are working with The Chart on indexing these identity structures which will open many new opportunities in this world.
If you also require a way of storing and handling user data, you have three main choices. Utilize the IDX library to directly save documents on the Ceramic Network and include references to those documents in the user's index. For this choice, no additional software application is needed; it works out of package with IDX.Store information in alternative information storage systems such as Filecoin, IPFS, Sia, Arweave, Fabric, Orbit, DB, Secure Data Stores, or Ethereum agreements and use IDX to add references to this data in your user's index.
This holds true despite where the information lives (servers or decentralized networks) or which application initially developed the information. The identity index includes mappings to different data sources, Share data across applications and silos, As explained above, the essential aspect of IDX that de-silos details, promotes interoperability, and allows user control is the identity index.
The identity index functions as the info root for each user and makes whatever visible. To even more promote interoperability, the identity index allows developers to: Release schemas, names, and descriptions for information points they are contributing to the index, so others can more quickly consume this information, Release endpoints for where this details can be found, whether a Doc, ID on Ceramic, a CID on IPFS/Filecoin, a contract on Ethereum, or an endpoint for a hosted service, Request consent to access encrypted information points in the index, Developing with IDXThe following section details how to begin constructing with IDX.
Setup, First, we'll require to install the primary IDX library and associated dependencies: npm set up @ceramicnetwork/ ceramic-http-client @ceramicstudio/ idx @ceramicstudio/ idx-constants, Query an identity, Then we can utilize these libraries to connect IDX to a Ceramic network and communicate with the files associated to a provided DID. This example demonstrates how to simply query the standard profile for a given Ceramic from '@ceramicnetwork/ ceramic-http-client' import IDX from '@ceramicstudio/ idx' import definitions from '@ceramicstudio/ idx-constants'// Use Ceramic devnetconst ceramic = new Ceramic('< https://ceramic.
