+# Thing Model Catalog
+## Worflow Description
+
+This design document proposes a user experience for the catalog interface derived from the design goals described in issue [#8].
+
+### Consumption
+
+**Simple Search:**
+
+A user want to use the official Thing Model catalog and downloads the ```tm-catalog-cli``` to interact with it. running it without paramters yields:
+
+```
+Usage:
+  tm-catalog-cli [command]
+  
+Available Commands:
+  add-repo
+  login
+  list
+  search
+  pull
+  push
+  create-toc
+  validate
+
+Flags:
+  -h, --help   help for tm-catalog-cli
+```
+
+The user wants to find a Thing Model for the Siemens PowerCenter 1000 data transceiver and tries the following:
+
+```
+> ./tm-catalog-cli list powercenter
+
+NAME                                 DESCRIPTION                                         STARS    QUALITY
+enrico/pc1000-7KN1110.tm.jsonld      Well tested TM for Siemens PC1000 transceiver       40       Syn/Sem/Run/Man
+siemens/7KN1110-0MC00.tm.jsonld      PowerCenter1000 transceiver official Thing Model    10       Syn/Sem/Run/-
+thomas/powercenter1000.tm.jsonld     TM for the Siemens PowerCenter1000                  3        Syn/-/-/-
+```
+
+The user now wants to pick the TM with the most stars and use it:
+
+```
+> ./tm-catalog-cli fetch enrico/pc1000-7KN1110.jsonld
+** Fetching enrico/pc1000-7KN1110.jsonld successful
+```
+
+and finds the file in the local directory. The user wants to find a TM for the arc fault detection device (AFDD) connected to the power center communication module, but the official catalog does not have a version available:
+
+```
+> ./tm-catalog-cli list afdd
+
+NAME                                 DESCRIPTION                                         STARS    QUALITY
+
+```
+
+The user now searches the catalog of his/her organization, but needs to login beforehand:
+
+```
+> ./tm-catalog-cli add-repo thing-catalog.siemens.com
+** Login to thing-catalog.siemens.com successful
+```
+
+Running the search again yields a hit:
+
+```
+> ./tm-catalog-cli list afdd
+
+NAME                                 DESCRIPTION                                         STARS    QUALITY
+siemens/wot_AFDDEM.jsonld            Official Thing Model for the AFDD module            20       Syn/Sem/Run/-
+```
+
+The user downloads it and starts using the Thing Model with their own WoT consumer
+
+```
+> ./tm-catalog-cli fetch siemens/wot_AFDDEM.jsonld
+** Fetching siemens/wot_AFDDEM.jsonld successful
+```
+
+**Custom Catalog:**
+
+The user has written some Thing Models for the current project, but they are not yet ready to be pushed to the companies or public catalogs. He/she wants to host them in a project-specific catalog. He creates a directory locally and imports his/her TMs:
+
+```
+> mkdir mycatalog; cd mycatalog
+> tm-catalog-cli import ../thingmodels/*jsonld
+** JSON Schema validation passed
+** JSONLD Syntactic validation passed
+** 1 Thing Model imported succesfully
+** Table of Content created
+
+> find .
+doe/Siemens/3NACOM_FUSE/smartfuse.jsonld
+catalog.toc.json
+```
+
+To test the catalog locally, the user runs an http-server on the directory:
+```
+> live-server .
+Live server running on localhost port 8080
+```
+
+Searching with the cli works:
+```
+> tm-catalog-cli list --catalog-url=http://localhost:8080 "smart fuse"
+NAME                                       DESCRIPTION                                         STARS    QUALITY
+Siemens/3NACOM_FUSE/smartfuse.jsonld       WIP Thing Model for Siemens smart fuse              0        Syn/Sem/-/-
+```
+
+Now the user creates a git repository, adds all the files and pushes it to his/her github account at https://www.github.com/doe
+```
+> git init .
+> git add .
+> git commit -m "inital commit of TMs for project valhalla"
+> git push --set-upstream git@github.com:doe/mycatalog
+```
+
+The user then adds this new repository to the list of registered repositories with the following command:
+```
+> tm-catalog-cli add-repo www.github.com:doe/mycatalog
+** Registered catalog at https://raw.githubusercontent.com/doe/mycatalog
+** Catalog contains 1 Thing Model
+```
+
+Running the search again without specifying the catalog URL works:
+```
+> tm-catalog-cli list "smart fuse"
+NAME                                       DESCRIPTION                                         STARS    QUALITY
+Siemens/3NACOM_FUSE/smartfuse.jsonld       WIP Thing Model for Siemens smart fuse              0        Syn/Sem/-/-
+```
