-# Ingestor
-OpenEM Data Network Ingestor service and app
+# OpenEm Data Network Ingestor
+
+This repository provides an ingestion app and service for dataset transfer and metadata registration in a catalog. It targets [Scicat](https://scicatproject.github.io) as dataset catalog.
+
+Data can be transfered via [Globus](https://www.globus.org) or via S3 to a compatible endpoint.
+
+There are two entrypoints, i.e. applications: a [desktop app](./cmd/openem-ingestor-app/) providing a minimal UI and a headless [service](./cmd/openem-ingestor-service/). Both provide a REST API in order to interact with each. Common functionality is extracted in the [core](./internal/) package.
+
+## Core
+
+The core package contains shared functionality between the desktop app and the service. It makes use of the [scicat-cli tools](https://github.com/paulscherrerinstitute/scicat-cli/tree/main) for interactions with Scicat. Two APIs are provided; a REST API for it interact with it as a service, and a Go API to interact with it within the same application.
+
+## Desktop App
+
+The desktop app is based on [wails.io](https://wails.io) which provides bindings between Go and typscript in order to write portable frontends in various web frameworks. Svelte was chosen in this case.
+
+For development wails provides hot reload capabilities:
+
+```bash
+../Ingestor/desktop-app> wails dev
+```
+
+And a build command to build frontend and backend into a single executable:
+
+```bash
+../Ingestor/desktop-app> wails build
+```
+
+see [wails.io](https://wails.io) for details.
+
+## Service
+
+```bash
+../Ingestor/desktop-app> go build
+```
+
+## Debugging
+
+[launch.json](.vscode/launch.json) and [task.json](.vscode/tasks.json) are provided to define debug targets for VS Code.

+# Svelte + TS + Vite
+
+This template should help get you started developing with Svelte and TypeScript in Vite.
+
+## Recommended IDE Setup
+
+[VS Code](https://code.visualstudio.com/)
+
++ [Svelte](https://marketplace.visualstudio.com/items?itemName=svelte.svelte-vscode).
+
+## Need an official Svelte framework?
+
+Check out [SvelteKit](https://github.com/sveltejs/kit#readme), which is also powered by Vite. Deploy anywhere with its
+serverless-first approach and adapt to various platforms, with out of the box support for TypeScript, SCSS, and Less,
+and easily-added support for mdsvex, GraphQL, PostCSS, Tailwind CSS, and more.
+
+## Technical considerations
+
+**Why use this over SvelteKit?**
+
+- It brings its own routing solution which might not be preferable for some users.
+- It is first and foremost a framework that just happens to use Vite under the hood, not a Vite app.
+  `vite dev` and `vite build` wouldn't work in a SvelteKit environment, for example.
+
+This template contains as little as possible to get started with Vite + TypeScript + Svelte, while taking into account
+the developer experience with regards to HMR and intellisense. It demonstrates capabilities on par with the
+other `create-vite` templates and is a good starting point for beginners dipping their toes into a Vite + Svelte
+project.
+
+Should you later need the extended capabilities and extensibility provided by SvelteKit, the template has been
+structured similarly to SvelteKit so that it is easy to migrate.
+
+**Why `global.d.ts` instead of `compilerOptions.types` inside `jsconfig.json` or `tsconfig.json`?**
+
+Setting `compilerOptions.types` shuts out all other types not explicitly listed in the configuration. Using triple-slash
+references keeps the default TypeScript setting of accepting type information from the entire workspace, while also
+adding `svelte` and `vite/client` type information.
+
+**Why include `.vscode/extensions.json`?**
+
+Other templates indirectly recommend extensions via the README, but this file allows VS Code to prompt the user to
+install the recommended extension upon opening the project.
+
+**Why enable `allowJs` in the TS template?**
+
+While `allowJs: false` would indeed prevent the use of `.js` files in the project, it does not prevent the use of
+JavaScript syntax in `.svelte` files. In addition, it would force `checkJs: false`, bringing the worst of both worlds:
+not being able to guarantee the entire codebase is TypeScript, and also having worse typechecking for the existing
+JavaScript. In addition, there are valid use cases in which a mixed codebase may be relevant.
+
+**Why is HMR not preserving my local component state?**
+
+HMR state preservation comes with a number of gotchas! It has been disabled by default in both `svelte-hmr`
+and `@sveltejs/vite-plugin-svelte` due to its often surprising behavior. You can read the
+details [here](https://github.com/rixo/svelte-hmr#svelte-hmr).
+
+If you have state that's important to retain within a component, consider creating an external store which would not be
+replaced by HMR.
+
+```ts
+// store.ts
+// An extremely simple external store
+import { writable } from 'svelte/store'
+export default writable(0)
+```

+SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
+-----------------------------------------------------------
+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide
+development of collaborative font projects, to support the font creation
+efforts of academic and linguistic communities, and to provide a free and
+open framework in which fonts may be shared and improved in partnership
+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded, 
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.
+
+DEFINITIONS
+"Font Software" refers to the set of files released by the Copyright
+Holder(s) under this license and clearly marked as such. This may
+include source files, build scripts and documentation.
+
+"Reserved Font Name" refers to any names specified as such after the
+copyright statement(s).
+
+"Original Version" refers to the collection of Font Software components as
+distributed by the Copyright Holder(s).

+writer or other person who contributed to the Font Software.
+

+in the appropriate machine-readable metadata fields within text or
+binary files as long as those fields can be easily viewed by the user.
+
+3) No Modified Version of the Font Software may use the Reserved Font
+Name(s) unless explicit written permission is granted by the corresponding
+Copyright Holder. This restriction only applies to the primary font name as
+presented to the users.
+
+4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
+Software shall not be used to promote, endorse or advertise any
