• Tags and levels are used to label an item(users, tasks, etc) and its difficulty/experience level respectively.
• Each document in ItemTags will be an item(users, tasks, etc) having a tagid, itemid, its type and also levelid, all referring to its corresponding document in Tag and Level collection.
• This type of modelling enables assigning tags to any item and also doing a different level assignment to the things.
• For a task, some typical documents will look like;

    {
        itemid: taskid,
        tagid: some_id_feature_react
        tagname: REACT,
        tagtype: SKILL,
        itemType: TASK,
        levelid: some_id_level_4
        levelname: advanced,
        levelnumber: 4
    }

• For an user, some typical documents will look like;

    {
        itemid: userid_deipayan,
        tagid: some_id_software_engineer,
        tagtype: USER,
        tagname: SOFTWARE-ENGINEER,
        itemType: USER,
        levelid: some_id_level_3,
        levelname: pro,
        levelnumber: 3,
    },
    {
        itemid: userid_deipayan,
