By many other standards, most of them "arrived" long ago - a couple of black lawyers from respected uptown law firms; a highly visible top executive of the phone company; a self-described professional "art activist" and political dabbler, and the president of one of the largest black-owned hotels in the country.

They are no stangers to local government in the District of Columbia. Two have been there before. One is there now.

But until today, when Mayor-elect Marion Barry is expected to announce that they will make up his transition team, most of these 13 people have been only at the periphery of political power.

Now they will exercise tremendous power and influence as the people helping Barry to establish priorities, develop policy and pick the key persons to run the District of Columbia government for the next four years.

The 13-member transition team, which is to be formally announced by Barry at a noon press conference today, suggests in its own make-up and stated goals that when Barry is inaugurated Jan. 2, the reins of District government will be passed to a decidely different breed of Washingtonians.

In its initial discussions, the transition team has talked about bringing into government people who would show a new commitments to the District of Columbia - two original team members were reduced to the lesser role of adviser because they did not live in the city - and have some track record of successful experience in related jobs.

In addition, said transition team chairman Delano E. Lewis, a vice president at C&P Telephone Co., the new city department heads will be those who can assume "a sort of Marion Barry role, [be] an aggressive person . . . in the same mold that you'll see in mayor's office."

In very few instances have names been matched with the jobs yet. "We're not going to have 15 people to announce on Jan. 2. We're just gonna have to play it by ear," Lewis said.

The members of the transition team, in addition to Lewis, are the Rev. Raymond B. Kemp, who served on the D.C. Board of Education while Barry was its president; Courtland Cox, like Barry a former member of the Student Non-violent Coordinating Committee who has since been active in programs concerning U.S. policy toward Africa; Gladys Mack, the currently city's deputy budget director; and Lillian Adkins Sedgwick, vice chairman of the D.C. Democratic State Committee.

Also Vincent H. Cohen, a partner in the Hogan & Hartson law firm and chairman of Clifford L. Alexander's 1974 campaign for mayor; Frederick B. Abramson of the Sachs, Greenebaum and Tayler law firm and a member of the D.C. Judicial Nomination Commission; economist Margaret Reuss of the University of the District of Columbia; and James Alexander, former director of the D.C. Department of Environmental Services.

The other members are James O. Gibson, a longtime friend of Barry who is an urban planner with the Potomac Institute and president of the minority-owned Harambee House hotel, Peggy Cooper, a lawyer active in varlous fine arts programs; Aletha Campbell, who has been president of the D.C. Congress of PTAs; and Anita Shelton, a former Washington Urban Leaque official now affiliated with the National Committee on Household Employment.

The two original task force members who will now act as advisers are [WORD ILLEGIBLE] M. Dearborn, vice president of the Center for Municipal and Metropolitan Research, and housing specialist James B. Harvey.

Lewis said he has already received about 25 resumes from people looking for jobs and, as is customary in any winning political campaign, lists of potential appointees have begun to circulate within Barry's inner circle.

Even at Barry's Tuesday night victory party at the Harambee House hotel there were several persons who said they hoped their support for Barry would result in a job in the administration.

Others at the victory party, members of various interest groups that supported Barry's come-from-behind victory, were letting it be known that they expected more than a handshake for their efforts.

"They owe and they have to pay," said Sonia Gutierrez, president of the Council of Hispanic Agencies, who contended that Barry would not have won the close September Democratic primary without the help of Latino voters.

Wilbur Hughes, a self-employed marketing and advertising consultant who had previously worked in mental health, was also at the victory celebration.

"I'm not going to rush up with a resume in my hand. I mean it will be his decision," Hughes said of Barry. "But I'm really trying to decide whether I want to continue being self-employed or go to the Barry administration. Right now, I'm leaning toward the Barry administration."

Barry himself had his own list of persons yesterday morning as he slumped into the high-backed chair in his City Council office on the first floor of the Distric Building.

For the 42-year-old at-large council member, savoring Tuesday's resounding victory over Republican Arthur A. Fletcher and two others took a back seat yesterday to pondering the realities of taking over a $1 billion-a-year, 44,000-worker bureaucracy.

How did it feel, a reporter asked, shortly after Barry has stepped out of the green campaign sedan, left his wife Effi in the back seat with a dozen roses and strolled up the stairs to his council office.

"It's a mixture of joy," Barry began, "and - I'm trying to think of the word - well, it's a lot of responsibility. I think about that more than I think about anything else."

Barry finally received yesterday an official concession from Fletcher, who refused to concede defeat early yesterday morning even though returns showed him trailing Barry by a margin of more than 2-to-1.

"Congratulations," Fletcher wrote in a hand-delivered letter. "You, your campaign organization, and hard working supporters are to be commended for the quality of your campaign and decisive victory in the November 7 election.

"Restoring faith in elected, appointed and career public servants and confidence in the governing process is at the very top of the national agenda. I know you will do your very best to achieve this objective in your management of District government affairs."

Barry spent only a few minutes in the hallways of the District Building yesterday, getting the customary pecks on the cheek from admiring female workers who addressed him as "Mr. Mayor," and one of whom remarked after Barry returned the greeting," A kiss from the mayor-elect - should I wash my face?"

The rest of the time he closeted himself in his office, sometimes with his campaign manager and alter ego Ivanhoe Donaldson, to further plan "the Barry administration" he had so often talked of as a candidate.

Transition team members believe that one of the first problems facing Barry is getting a handle on the city's sprawling bureaucracy, a patchwork of individual-minded agencies scattered throughout more than a dozen buildings.

"Nobody knows what's really inside that government. I don't even know if Walter Washington knows," one team member said privately.

The key position in government is considered by many to be that of city administrator, a post now held by Julian R. Dugas, a longtime friend and ally of Mayor Washington. The Barry administration, according to one source, will face two problems in connection with the city administration's post.

Dugas, who was director of the city's former Department of Economic Development (now the Department of Licenses, Permits and Inspections) has sufficient civil service protection to resume that post once he is removed as city administrator, as Barry has pledged to do.

Filling Dugas' job could also be difficult for the Barry administration, some of those advising Barry believe, because it may be difficult to find someone with the necessary experience to meet Barry's qualifications of being "compassionate and competent."

Many around Barry have suggested privately that the new city administrator be black, as Dugas is. But not many blacks have had that kind of experience, one observer noted.
