Overview

Complete installation steps and add the following imports:

from gemd import MaterialTemplate, ProcessTemplate, MeasurementTemplate

from openmsimodel.science_kit.science_kit import ScienceKit
from openmsimodel.tools.structures.materials_sequence import MaterialsSequence
from openmsimodel.entity.gemd.material import Material
from openmsimodel.entity.gemd.process import Process
from openmsimodel.entity.gemd.measurement import Measurement
from openmsimodel.db.open_db import OpenDB
from openmsimodel.graph.open_graph import OpenGraph

from pathlib import Path

Then, start interacting with OpenMSIModel by:

• Building a GEMD Object and wrap it with a Element class:

process = Process("Heating", template=ProcessTemplate("Heating"))
material = Material("Heated Alloy", template=MaterialTemplate("Heated Alloy"))

• Organize them as desired, and encapsulates all your knowledge and tools in your science kit:

w = ScienceKit()
block = MaterialsSequence(
     name=f"Heating Block",
     science_kit=w,
     material=material,
     ingredients={},
     process=process,
     measurements={},
)
block.link_within() # 4 links completed in one statement

• Visualize your objects with OpenGraph:

to_be_visualized = block.return_all_gemd()
output = str(Path().absolute() / "output")
print(output)
assets_to_add = {
        "add_attributes": 1,
        "add_file_links": 1,
        "add_tags": 1,
    }
open_graph = OpenGraph("Heating Block", dirpath=to_be_visualized, output=output, layout='visualization', add_bidirectional_edges=False)
G, relabeled_G, name_mapping = open_graph.build_graph(
    assets_to_add=assets_to_add,
    add_separate_node=False,
    which='all',
)

• Query them with OpenDB:

db_name = "GEMD"
open_db = OpenDB(database_name=db_name, private_path="/path/to/private/key", output=output)

table_name = "heating_block_table"
open_db.load_model(table_name, dirpath=output)
open_db.custom_query("select top 3 context from gemdobject c where c.model_id={}".format(table_name))
