 # Maps API
 
-The CartoDB Maps API allows you to generate maps based on data hosted in your CartoDB account and apply custom SQL and CartoCSS to the data. The API generates a XYZ-based URL to fetch Web Mercator projected tiles, using web clients such as [Leaflet](http://leafletjs.com), [Google Maps](https://developers.google.com/maps/), or [OpenLayers](http://openlayers.org/).
+The CARTO Maps API allows you to generate maps based on data hosted in your CARTO account and apply custom SQL and CartoCSS to the data.

 You can create two types of maps with the Maps API:
 
-- **Anonymous maps**  
-  You can create maps using your CartoDB public data. Any client can change the read-only SQL and CartoCSS parameters that generate the map tiles. These maps can be created from a JavaScript application alone and no authenticated calls are needed. See [this CartoDB.js example](/cartodb-platform/cartodb-js/getting-started/).

+# 1. Purpose
+
+This specification describes an extension for
+[MapConfig 1.4.0](https://github.com/CartoDB/Windshaft/blob/master/doc/MapConfig-1.4.0.md) version.
+
+
+# 2. Changes over specification
+
+This extension targets layers with `sql` option, including layer types: `cartodb`, `mapnik`, and `torque`.
+
+It extends MapConfig with a new attribute: `analyses`.
+
+## 2.1 Analyses attribute
+
+The new analyses attribute must be an array of analyses as per [camshaft](https://github.com/CartoDB/camshaft). Each
+analysis must adhere to the [camshaft-reference](https://github.com/CartoDB/camshaft/blob/0.8.0/reference/versions/0.7.0/reference.json) specification.
+
+Each node can have an id that can be later references to consume the query from MapConfig's layers.
+
+Basic analyses example:
+
+```javascript
+[
+    {
+        // REQUIRED
+        // string, `id` free identifier that can be reference from any layer
+        "id": "HEAD",
+        // REQUIRED
+        // string, `type` camshaft's analysis type
+        "type": "source",
+        // REQUIRED
+        // object, `params` will depend on `type`, check camshaft-reference for more information
+        "params": {
+            "query": "select * from your_table"
+        }
+    }
+]
+```
+
+# 2.2. Integration with layers
+
+As pointed before an analysis node id can be referenced from layers to consume its output query.
+
+The layer consuming the output must reference it with the following option:
+
+```
+{
+    "options": {
+        // REQUIRED
+        // object, `source` as in the future we might want to have other source options
+        "source": {
+            // REQUIRED
+            // string, `id` the analysis node identifier
+            "id": "HEAD"
+        }
+    }
+}
+```

+# 1. Purpose
+
+This specification describes an extension for
+[MapConfig 1.4.0](https://github.com/CartoDB/Windshaft/blob/master/doc/MapConfig-1.4.0.md) version.
+
+
+# 2. Changes over specification
+
+This extension depends on Analyses extension. It extends MapConfig with a new attribute: `dataviews`.
+
+It makes possible to get tabular data from analysis nodes: lists, aggregated lists, aggregations, and histograms.
+
+## 2.1. Dataview types
+
+### List
+
+A list is a simple result set per row where is possible to retrieve several columns from the original layer query.
+
+Definition
+```
+{
+    // REQUIRED
+    // string, `type` the list type
+    “type”: “list”,
+    // REQUIRED
+    // object, `options` dataview params
+    “options”: {
+        // REQUIRED
+        // array, `columns` to select for the list
+        “columns”: [“name”, “description”]
+    }
+}
+```
+
+Expected output
+```
+{
+  "type": "list",
+  "rows": [
+    {
+      "{columnName1}": "val1",
+      "{columnName2}": 100
+    },
+    {
+      "{columnName1}": "val2",
+      "{columnName2}": 200
+    }
+  ]
+}
+```
+
+### Aggregation
+
+An aggregation is very similar to a list but results are aggregated by a column and a given aggregation function.
+
+Definition
+```
+{
+    // REQUIRED
+    // string, `type` the aggregation type
+    “type”: “aggregation”,
+    // REQUIRED
+    // object, `options` dataview params
+    “options”: {
+        // REQUIRED
+        // string, `column` column name to aggregate by
+        “column”: “country”,
+        // REQUIRED
+        // string, `aggregation` operation to perform
+        “aggregation”: “count”
+        // OPTIONAL
+        // string, `aggregationColumn` column value to aggregate
+        // This param is required when `aggregation` is different than "count"
+        “aggregationColumn”: “population”
+    }
+}
+```
+
+Expected output
+```
+{
+  "type": "aggregation",
+  "categories": [
+    {
+      "category": "foo",
+      "value": 100
+    },
+    {
+      "category": "bar",
+      "value": 200
+    }
+  ]
+}
+```
+
+### Histograms
+
+Histograms represent the data distribution for a column.
+
+Definition
+```
+{
+    // REQUIRED
+    // string, `type` the histogram type
+    “type”: “histogram”,
+    // REQUIRED
+    // object, `options` dataview params
+    “options”: {
+        // REQUIRED
+        // string, `column` column name to aggregate by
+        “column”: “name”,
+        // OPTIONAL
+        // number, `bins` how many buckets the histogram should use
+        “bins”: 10
+    }
+}
+```
+
+Expected output
+```
+{
+  "type": "histogram",
+  "bins": [{"bin": 0, "start": 2, "end": 2, "min": 2, "max": 2, "freq": 1}, null, null, {"bin": 3, "min": 40, "max": 44, "freq": 2}, null],
+  "width": 10
+}
+```
+
+### Formula
+
+Formulas given a final value representing the whole dataset.
+
+Definition
+```
+{
+    // REQUIRED
+    // string, `type` the formula type
+    “type”: “formula”,
+    // REQUIRED
+    // object, `options` dataview params
+    “options”: {
+        // REQUIRED
+        // string, `column` column name to aggregate by
+        “column”: “name”,
+        // REQUIRED
+        // string, `aggregation` operation to perform
+        “operation”: “count”
+    }
+}
+```
+
+Operation must be: “min”, “max”, “count”, “avg”, or “sum”.
+
+Result
+```
+{
+  "type": "formula",
+  "operation": "count",
+  "result": 1000,
+  "nulls": 0
+}
+```
+

+## 2.2 Dataviews attribute

+The new dataviews attribute must be a dictionary of dataviews.
+
+An analysis node id can be referenced from dataviews to consume its output query.
+
+
+The layer consuming the output must reference it with the following option:
+
+```
+{
+    // REQUIRED
+    // object, `source` as in the future we might want to have other source options
+    "source": {
+        // REQUIRED
+        // string, `id` the analysis node identifier
+        "id": "HEAD"
+    }
+}
+```
+
+## 2.3. Complete example
+
+```
+{
+    "version": "1.4.0",

+
+## 3. Filters
+
+Camshaft's analyses expose a filtering capability and `aggregation` and `histogram` dataviews get them for free with
+ this extension. Filters are available with the very dataview id, so if you have a "basic_histogram" histogram dataview
+ you can filter with a range filter with "basic_histogram" name.
+
+
+## 3.1 Filter types
+
+### Category
+
+Allows to remove results that are not contained within a set of elements.
+Initially this filter can be applied to a `numeric` or `text` columns.
+
+Params
+
+```
+{
+    “accept”: [“Spain”, “Germany”]
+    “reject”: [“Japan”]
+}
+```
+
+### Range filter
+
+Allows to remove results that don’t satisfy numeric min and max values.
+Filter is applied to a numeric column.
+
+Params
+
+```
+{
+    “min”: 0,
+    “max”: 1000
+}
+```
+
+## 3.2. How to apply filters
+
+Filters must be applied at map instantiation time.
+
+With :mapconfig as a valid MapConfig and with :filters (a valid JSON) as:
+
+### Anonymous map
+
+`GET /api/v1/map?config=:mapconfig&filters=:filters`
+
+`POST /api/v1/map?filters=:filters`
+with `BODY=:mapconfig`
+
+If in the future we need to support a bigger filters param and it doesn’t fit in the query string,
+ we might solve it by accepting:
+
+`POST /api/v1/map`
+with `BODY={“config”: :mapconfig, “filters”: :filters}`
+
+### Named map
+
+Assume :params (a valid JSON) as named maps params, like in: `{“color”: “red”}`
+
+`GET /api/v1/named/:name/jsonp?config=:params&filters=:filters&callback=cb`
+
+`POST /api/v1/named/:name?filters=:filters`
+with `BODY=:params`
+
+If, again, in the future we need to support a bigger filters param that doesn’t fit in the query string,
+ we might solve it by accepting:
+
+`POST /api/v1/named/:name`
+with `BODY={“config”: :params, “filters”: :filters}`
+
+
+## 3.3 Bounding box special filter
+
+A bounding box filter allows to remove results that don’t satisfy a geospatial range.
+
+The bounding box special filter is available per dataview and there is no need to create a bounding box definition as
+it’s always possible to apply a bbox filter per dataview.
+
+A dataview can get its result filtered by bounding box by sending a bbox param in the query string,
+param must be in the form `west,south,east,north`.
+
+So applying a bbox filter to a dataview looks like:
+GET /api/v1/map/:layergroupid/dataview/:dataview_name?bbox=-90,-45,90,45

 Some notes about filtering:
 
   - Invalid index values or out of bounds indexes will end in `Invalid layer filtering` errors.
-  - Once a mapnik layer is selected, all mapnik layers will get blended. As this may change in the future **it is
-  recommended** to always select all mapnik layers if you want to select at least one so you will get a consistent
-  behavior in the future.
   - Ordering is not considered. So right now filtering layers 0,3,4 is the very same thing as filtering 3,4,0. As this
   may change in the future **it is recommended** to always select the layers in ascending order so you will get a
   consistent behavior in the future.

 # Named Maps
 
-Named maps are essentially the same as anonymous maps except the MapConfig is stored on the server, and the map is given a unique name. You can create named maps from private data, and users without an API Key can view your Named Map (while keeping your data private). The Named map workflow consists of making a call to your database, referencing a table, inserting your variables into the template where placeholders are defined, and creating custom queries.
+Named Maps are essentially the same as Anonymous Maps except the MapConfig is stored on the server, and the map is given a unique name. You can create Named Maps from private data, and users without an API Key can view your Named Map (while keeping your data private).
 
-The main two differences compared to anonymous maps are:
+The Named Map workflow consists of uploading a MapConfig file to CARTO servers, to select data from your CARTO user database by using SQL, and specifying the CartoCSS for your map.
 
-- **auth layer**  
-  This allows you to control who is able to see the map based on a token auth
+The response back from the API provides the template_id of your Named Map as the `name` (the identifier of your Named Map), which is the name that you specified in the MapConfig. You can  which you can then use to create your Named Map details, or [fetch XYZ tiles](#fetching-xyz-tiles-for-named-maps) directly for Named Maps.
 
-- **templates**  
-  Since the MapConfig is static it can contain some variables so the client can modify the map's appearance using those variables.
+**Tip:** You can also use a Named Map that you created (which is defined by its `name`), to create a map using CARTO.js. This is achieved by adding the [`namedmap` type](http://docs.carto.com/carto-engine/carto-js/layer-source-object/#named-maps-layer-source-object-type-namedmap) layer source object to draw the Named Map.
 
-Template maps are persistent with no preset expiration. They can only be created or deleted by a CartoDB user with a valid API_KEY (see auth section).
+The main differences, compared to Anonymous Maps, is that Named Maps include:
 
-**Note:** There is a limit of 4,096 named maps allowed per account. If you need to create more Named maps, it is recommended to use templates.
+- **auth token**  
+  This allows you to control who is able to see the map based on an auth token, and create a secure Named Map with password-protection.
+
+- **template map**  
+  The template map is static and may contain placeholders, enabling you to modify your maps appearance by using variables. Templates maps are persistent with no preset expiration. They can only be created, or deleted, by a CARTO user with a valid API KEY (See [auth argument](#arguments)).
+
+  Uploading a MapConfig creates a Named Map. MapConfigs are uploaded to the server by sending the server a "template".json file, which contain the [MapConfig specifications](http://docs.carto.com/carto-engine/maps-api/mapconfig/).
+
+**Note:** There is a limit of 4,096 Named Maps allowed per account. If you need to create more Named Maps, it is recommended to use a single Named Map and change the variables using [placeholders](#placeholder-format), instead of uploading multiple [Named Map MapConfigs](http://docs.carto.com/carto-engine/maps-api/mapconfig/#named-map-layer-options).

+
+## Fetching XYZ Tiles for Named Maps
+
+Optionally, authenticated users can fetch projected tiles (XYZ tiles or Mapnik Retina tiles) for your Named Map.
+
+### Fetch XYZ Tiles Directly with a URL
+
+Authenticated users, with an auth token, can use XYZ-based URLs to fetch tiles directly, and instantiate the Named Map as part of the request to your application. You do not have to do any other steps to initialize your map.
+
+To call a template_id in a URL:
+
+`/{template_id}/{layer}/{z}/{x}/{y}.{format}`
+
+For example, a complete URL might appear as:
+
+"https://{username}.carto.com/api/v1/map/named/{template_id}/{layer}/{z}/{x}/{y}.png"
+
+The placeholders indicate the following:
+
+- [`template_id`](http://docs.carto.com/carto-engine/maps-api/named-maps/#response) is the response of your Named Map.
+- layers can be a number (referring to the # layer of your map), all layers of your map, or a list of layers.
+  - To show just the basemap layer, enter the number value `0` in the layer placeholder "https://{username}.carto.com/api/v1/map/named/{template_id}/0/{z}/{x}/{y}.png"
+  - To show the first layer, enter the number value `1` in the layer placeholder "https://{username}.carto.com/api/v1/map/named/{template_id}/1/{z}/{x}/{y}.png"
+  - To show all layers, enter the value `all` for the layer placeholder "https://{username}.carto.com/api/v1/map/named/{template_id}/all/{z}/{x}/{y}.png"
+  - To show a [list of layers](http://docs.carto.com/carto-engine/maps-api/anonymous-maps/#blending-and-layer-selection), enter the comma separated layer value as 0,1,2 in the layer placeholder. For example, to show the basemap and the first layer, "https://{username}.carto.com/api/v1/map/named/{template_id}/0,1/{z}/{x}/{y}.png"
+
+
+### Get Mapnik Retina Tiles
+
+Mapnik Retina tiles are not directly supported for Named Maps, so you cannot use the Named Map template_id. To fetch Mapnik Retina tiles, get the [layergroupid](http://docs.carto.com/carto-engine/maps-api/named-maps/#response-1) to initialize the map.
+
+Instantiate the map by using your `layergroupid` in the token placeholder:
+
+ `{token}/{z}/{x}/{y}@{scale_factor}?{x}.{format}`

 ### Caching
 
-It is important to note that generated images are cached from the live data referenced with the `layergroupid token` on the specified CartoDB account. This means that if the data changes, the cached image will also change. When linking dynamically, it is important to take into consideration the state of the data and longevity of the static image to avoid broken images or changes in how the image is displayed. To obtain a static snapshot of the map as it is today and preserve the image long-term regardless of changes in data, the image must be saved and stored locally.

 ### Limits
 
-* While images can encompass an entirety of a map, the default limit for pixel range is 8192 x 8192.
-* Image resolution by default is set to 72 DPI
-* JPEG quality by default is 85%
-* Timeout limits for generating static maps are the same across the CartoDB Editor and Platform. It is important to ensure timely processing of queries.
