Implicit tags are tags that get set automatically based either on the program schedule or in the case of the special tags ^channel and ^countdown. All implicit tags have prefix ^.

For program schedule tags, the general format has 3 parts delimited by periods:

1. channel name (optional and if left out, the current channel) - the channel name is case sensitive
2. which relative show (now , next, the show after that,...)
3. tag name

For example, ^ESPN1.now.hashtag is a tag that tells us to substitute the tag for the hashtag for the current show on channel ESPN1.

If we leave off the channel prefix and use the tag ^now.hashtag, we'd use the hashtag for the current show for the current channel being played out.The reason for having the optional channel part is to support cross channel promotion. For example, we might have a scene that has ^ESPN1.now.name and ^ESPN2.now.name and we would substitute the current show's name for each of those channels.This is a way of promoting what's on the current show and also another. There's no limit to the number of channels a scene can cross promote.

We have 2 special aliases for next tags:

1. ^now which is the same as ^next[0]
2. ^next which is the same as ^next[1]

Basically, they're just short forms for next[n] where n refers to the relative show based on the current show. For example, n = 0 is the current show, n = 1 is the next show, n = 2 is the show after that,...

In Chameleon we support both programs and episodes. That is, if a program is a series, when we schedule the program, we can specify the episode for the series show. There are several standard tags for programs and episodes but additional tags can be defined. We call these dynamic tags. Basically, dynamic tags are a way of attaching additional information to a program or episode. They can be text or media.

The standard tags for program are:

1. name
2. shortname
3. time (the start time for a scheduled program)
4. duration (the duration for the schedule program)
5. synopsis
6. hashtag
7. rating
8. firstaired
9. url

The standard tags for episodes are:

1. episode.name - the name of the episode
2. episode.season - the episode's season (integer)
3. episode.number - the episode's # in the season (integer)
4. episode.synopsis - the episode's synopsis
5. episode.firstaired
6. episode.url

We have special implicit tags that aren't related to the program channel:

1. ^channel - this is a way of inserting the channel's name into a scene
2. ^countdown - this is a countdown tag with the timestamp used to count down to defined in the asset in flow
3. ^time - long time as defined by system Date & Time but can be modified with a format suffix. eg: ^time[H:mm:ss] (updates every second)
4. ^date - short date as defined by system Date & Time but can be modified with a format string. eg: ^time[MMMM dd, yyyy] (updates every minute)

There's a special case for tags ^channel and rating tags. Both support text and logos. For logos, if there's a rating or channel directory, it'll try to use a logo. For example, if the rating for the show is PG and there's a logo in the rating directory called PG.pga, it'll be used.

For chameleon, we changed the format of most of the implicit tags.

All tag names are case insensitive. Here are some examples:
