Tag group

The first set of tag groups in the Niagara Haystack 4 tag dictionary are derived from the conjuncts (for example, ac-elec) defined in the defs.json file.

Figure 1. Example of conjunct tag groups


The co2-concentration conjunct becomes a co2Concentration tag group that contains the co2 and concentration tags.

Figure 2. Example of protos tag group


The next set of tag groups are created for all protos in Project Haystack’s protos.json file that are not already a tag or conjunct. For example, the “point” and “humidifier equip” protos are skipped because there is already a point tag and humidifierEquip conjunct tag group.
